I was a huge fan of MDK, but never got around to play MDK 2 back in the day.
Is the sequel as good as the first?
Your opinion?

MDK's average = 89.2%

IMHO, MDK 2 was more polished, but it made less of an impact as it wasn't as original as the first (blatantly obvious, being a sequel...)

MDK2 had a better 3d engine (it came later), but I didn't enjoy it as much as the first because the fluke Hawkins levels weren't much fun.

Don't think it's as good as the first, mainly because the first seemed so new and original. It's still a great game though, and really funny in parts, but yeah, as mentioned, some of the levels can be a bit annoying. I had to stop at a point where you were swimming around as a fish in some pipes (a Prof Hawkins level), got completely lost!

To be honest, I enjoyed MDK2 better than the first installment, mainly because of the different types of gameplay that you could find in the game. The Kurt Hectic levels are quite similar to those of MDK, but you also get to play Max (4 paws, 4 times the damage, and a jetpack) or Pr. Hawkins (more of a brain-teaser: combine objects into weapons of mass destruction!).
If you liked MDK, there's no reason you wouldn't like the second one. It's not exactly the same game, but the humour is still there, as well as the awesome gameplay.

Then I'll get MDK and use my free game purches to get MDK 2.
Thanx guy's! 8o)

To be honest, I didn't like the sequel as much. However, I think this may be because I played it on dreamcast back in the day and the control scheme was awful. If you like MDK though, you may as well get the second. The humor is still there and the atmosphere of the game is great.
Edit: I take this back; I judged unfairly. After having played through the 2nd I agree that the polish makes the game very enjoyable and I admit I got hooked on it til I beat it

Here's my brief review from this site:
"4/5 Difficult, but perfect for core gamers
This sequel does what every sequel is supposed to do: raise the stakes and give more to do. This time around, the players are given three different characters with three different play styles to mess around with. I found the most pleasure playing with Max, the multi-limbed dog, as his sections were full of explosions and lots of mayhem. Kurt's sections were much like the first game's -- a little sniping, a little parachuting, and we're good. Dr. Hawkins has the most interesting, if least-developed part of the game. His item-combining missions are mostly obnoxious fetch-quest and backtrack-heavy. On top of that, his missions are also heavy on combat, and he's not the most adept at handling the attacking critters. Come on...a radioactive projectile-spitting toaster?
In any case, the game is well-balanced and often very fun. The graphics look pretty crisp and nice over eight years later. The story and feel of the game is also expanded upon; it's much more absurd and has even more personality thanks to the technology at the time. There are some very intense platforming segments for all characters, though. Therefore, someone with an unbelievably precise hand - or a really nice gaming controller - will be able to successfully make his or her way though the latter parts of this game. Get to Max's jetpack levels to see what I mean.
This game is pretty intense and offers a lengthy play experience. It holds up today rather well, and has real ingenuity and personality behind it. Be warned again: game is hard and requires a steady hand and mind. It is also, however, fun, and keeps the spirit of the slightly superior, more consistent original. A solid sequel for fans of the genre and the original alike, but not for everyone."
I hope that helps.

For me, personally, the second one lacked the humor of the first one, and lacked a bit of the wackyness, the atmosphere, and (despite Jesper Kyd's also excellent soundtracks) lacked the symphonic, movie-like soundtrack by Tommy Tallarico. This was so good it got it's own CD release.
The reason, I believe, for their differences lie in the developers. MDK, was written by Shiny, a company already known for their wacky humor in the Earthworm Jim games, while MDK2, was written by Bioware. And while MDK2 was a great game, it didn't feel as good or groundbreaking as MDK.

No it is not.
They took out the open battlefield gameplay style and replaced it with a puzzle-strewn corridor shooter. Most of your enemies while playing as Kurt are tiny ceiling-mounted cameras. The main purpose of the sniper rifle in this game is opening glowing plasma ball door locks. Hitting an regular enemy with the sniper rifle in the head or in the leg makes no difference, and the weak spots on boss enemies are the exact same glowing plasma balls that you shoot to open doors.
The dog's levels are just dull. The scientist's levels are incredibly frustrating. Plus the scientists' vaunted "invent weapons on the fly" system is a huge dud as there is very little to invent, and most of his more powerful weapons are just handed to him by outside characters.
The game's one saving grace is funny cutscenes. If that's your selling point, you'd be better off getting a copy of Giants, which has funner cutscenes with tits.

IMO MDK1 is better then MDK2... But i love both parts :)

MDK1 is for me way better than the first one: it was more repetitive, but
1 Kurt is way more fun to control than any of the other
2 No crappy plateform sequence (save fall reload jump save fall reload fall reload fall reload...)
3 Using the zoom was more effective: it's frustrating to see enemies taking bullets in the head and staying as if nothing happened.
