#6 SQ4 Pros: Narrator voice, graphic. Cons totally wasted time travel potential, weak story, dead ends, frustrating puzzles
#5 SQ3: Pros: puzzles. Cons: no story at all, astro chicken!
#4 SQ6: Pros: good story and narration, voices, no dead ends. Cons: aimless wandering at begining, copy protection puzzles.
#3 SQ2: Pros best story and puzzles in EGA SQ era. Cons: difficulty, dead ends.
#2 SQ1: Pros: being the first, story, fairy easy compared to other "first part" Sierra titles, humor. Cons: dead ends, mini-games.
#1 SQ5: Pros: Best plot and characters in series, you are a captain of space craft!, only one(?) dead end. Cons: no voice acting, maze.

#6 SQ3 Pros: Good music, better graphics than the first 2 games. Cons: some really hard puzzles. How the hell is anyone supposed to figure out what to do at the beginning of the game? Also this game has some crappy mini-games, especially Astro-chicken. There is also a continuity error. The hallway in ScumSoft is unnecessarily difficult to walk through. Lastly, for me this was the least funny game in the series.

#5 SQ5 Pros: Cool storyline, good backgrounds, and Roger actually makes some friends. We even get to meet Beatrice Wankmeister. Also some parodies of space movies and TV shows, and even a parody of the fly. Cons: no voice acting, IMO the worst music in the series, a repetition of the continuity error in SQ3 (that error was bad enough the first time. And they repeated it?), no smell and taste, 2nd least funny game in the series. Pointless mini-game at the bar. Lastly, some incredibly frustrating parts of the game (the EVA pod, cheating on the test even though the rat supposedly screws with the test scores anyway, making a frog leap at you, miss, and land on the correct button on the communication thing, and the maze).

#4 SQ6 Pros: Good voice acting; Gary Owens returns! A lot of humor, especially in Roger's bedroom and the elevator on Delta Burksilon V. Roger becomes popular with the young ladies. The homing beacon puzzle (yes, I enjoyed that), Great music especially the Soylent jingle. A reference to one of the all-time great games "Gabriel Knight" (there's a familiar character from that game at Stellar's funeral. I quite liked the Inner Space Part of this game. Cons: Continuity error (how could Roger have successfully returned the Eureka in the intro when he blew it up in SQ5?) Going out of its as to pretend SQ5 never happened, never seeing Beatrice, Flo, Droole, Cliffy, or WD40, getting wrongfully demoted from captain after saving the universe. An unnecessary "upgrade" from VGA to SVGA (Why did Sierra do this? I liked VGA better). Many absurd puzzles I don't see how anyone could solve without luck or outside help. The cyberspace maze. The fact that the game is frustratingly long; the first time I played this I must have said "WHY WON'T THIS GAME END?" dozens of times to myself. Lastly, the game ends on a cliffhanger ending. The cliffhanger never gets resolved.

#3 SQ1: Pros: The game that started it all. It's both hilarious and fun for the whole family. The VGA remake has great music, and a cameo appearance from the 2 Guys From Andromeda in 2 of the deaths. Probably the best mini-game in the series (the skimmer). The VGA game has the best ending in the series (King Graham makes a cameo!). I also love that you can travel to "King's Quest" or "Conquests of the Longbow" depending on which version of the game you are playing. Cons: The original game has outdated graphics, a text parser, and unavoidable gambling. Both versions of the game have dead ends, including a very cruel dead end where it's easy to miss a jet pack that you need to beat the game.

#2 SQ2: Pros: The funniest game of the series IMO. In particular, I love the villain and his ridiculous plan. My favorite storyline in the series. Cons: Some bad puzzles including :Put gem in mouth" and "Hold breath." Some tough mazes like the root monster maze and the underground maze. However, these problems were corrected by Infamous Adventures VGA remake. One problem that was not corrected however is the worst ending I have ever seen in an adventure game.

#1 SQ4: Pros: Good voice acting, especially from Gary Owens. A storyline that is absurd, yet perfect for Space Quest. Great music especially the "Time to Format" music. Not many absurd puzzles. Not many dead ends. Great backgrounds. Latex Babes. The ability to return to previous "Space Quest" games, including the change of graphics when you visit an earlier game. Some good mini-games. Great humor. Cons: Eluding the Monochrome boys. I always have trouble doing this. It seems more absurd considering the only reason you need to encounter them is to get a box of matches. Eluding the Sequel Police and the Security Droids can be a headache as well. Also the part with the lasers at the entrance to the Supercomputer is quite frustrating if you don't know what to do.

Actually SQ5 has more than one dead end:

-Enter the EVA pod the second time (when you're about to board the Goliath) without the laser thing you need to cut your way into the ship.
-Enter the EVA pod the second time without having retrieved the liquid nitrogen tanks from Genetix.
-Enter the EVA pod the first time without the spare oxygen tank.
-Pressing the self-destruct button before you need to. You can abort the self-destruct, but everyone else on the ship will have already left the ship.

Also, I don't know if this counts as a death or a dead end or both, but if you spend too much time wandering around in the EVA Pod the first time, you'll have either not enough oxygen or not enough fuel to return to the ship with Cliffy.

Actually SQ5 has more dead ends than SQ4, so it's more than odd you list dead ends as a weakness in SQ4. The only dead end in that game is if you don't write down the time code for SQ12 and you don't keep a saved game back there.

I'm partial to, and most nostalgic for SQ3, but SQ2 was my first Space Quest (I remember literally comparing SQ1 and SQ2 boxes in my hands at Electronics Boutique and choosing SQ2 for no good reason other than my 12-year-old brain deciding it must be improved because it's the second one, sigh). SQ2 was a good game, though.

SQ3 was the jump to nicer graphics (ha ha, for Sierra) and an actual proper soundtrack! Also there was a better variety of environments and some great gags. It's also the first time I heard digitized sounds in a game on my family's Tandy 1000 TL/2! It establishes some neat new lore and world building.

I loved the more serious tone of SQ4, even though it retained a good deal of humor and satire... but that one only really kicked in for me with the fully voiced CD-ROM version. Gary Owens rocked as a narrator. It sucks that Sierra execs didn't bother with a talkie version of SQ5. I never played through SQ5, but will some day.

SQ6 had SVGA graphics finally, and I don't understand how people don't see that as a logical upgrade from the original pixel art art of the AGI and SCI games. Yes, I like the painted graphic novel style art in 4 and 5, but if we are to take this series as a comedy, I think the semi-realistic cartoonish look is appropriate. Plus, the voice-acting and narrator is present again. Some of the game was compromised by retreading old gags and executive meddling, but there's a lot to like.
