I took it, since I still had some credit on GMG... I don't know some of the games though, do you have some recommendations on what to try?
I've played more than my fair share of Sega, so...
Golden Axe: Good beat-'em-up. Not amazing, but fun.
Altered Beast: It was more like a tech demo, really. Fun, but as short as it is simple.
Comix Zone: A beat-'em-up game with more of a fighting game feel. Awesome comic-style presentation, but it's a bit on the hard side.
Ecco the Dolphin: Well, there's not a lot like it. It's a love it or hate it kind of thing. I love it. :P
Gain Ground: This game is cool! Get your guys from one side of the map to another while saving hostages who will join you.
Shinobi III: Here we go. Now this is some good shit. That's all that needs to be said.
Vectorman: One of the last platformers on the system. Very good platformer, flashy graphics.
Crack Down: It's pretty good.
Shadow Dancer: Not as good as Shinobi III, but still a great game. Very different from that game as well.
Space Harrier II: Good if you like this sort of thing. It's a simple rail-shooter.
Ecco Jr: Crap.
Alex Kidd in the Enchanted Castle: One of the weaker games in the series, but it's good fun. Definitely worth a try.
Bonanza Bros: This one is better two-player. Worth playing until you get bored of it.
Super Thunder Blade: Worst game in this bundle. It was garbage when it was new.
Kid Chameleon: Sega's
other other answer to Mario. Lots of levels and powerups, one of the best games in this bundle.
Ristar: ...and so is this. If you've managed to avoid playing this up until now, get the pack for this one. One of the last games on the system, and Sega really gave their best effort. It's one hell of a platformer. Great graphics, worlds, music, bosses, bonus levels, it just does everything right. Trust me, this one is good.
Galaxy Force II: Meh.
Columns: A good time waster, but there's a million other better puzzle games.
Eternal Champions: A pretty good fighting game. Sega CD version was better, but all the same, you'll probably want a good controller. For all of these games, really.
Fatal Labyrinth: Among the games I was upset wasn't in 'Sega Genesis Collection'. Wins the 'best title screen ever' award, having been my wallpaper for an eternity. It's a dungeon-crawler, a fairly simple roguelike. This is probably another love it or hate it game.
...and the second bundle:
Golden Axe II: Not as good as the first, but still pretty okay.
ESWAT: City Under Siege: It's pretty cool.
Flicky: A fun arcade game. Sega includes it in nearly every collection, though...
Decap Attack starring Chuck D. Head: This is actually a very good platformer. It has an item system, and sometimes you need to find a key to beat a level, so it's not totally linear.
Alien Swarm: It's alright.
Ecco: The Tides of Time: If you didn't like Ecco, you might still not like this one. A lot of people will agree it was a vast improvement, though.
Virtua Fighter 2: The real Virtua Fighter 2 is a great 3D fighting game (though, I'm a bigger fan of 2D fighting, really). This, unfortunately, is not the real Virtua Fighter 2. Play it for laughs.
Sword of Vermilion: The third gem on this list. Some people despise this game. It's a slow RPG, and as an old jRPG, you shouldn't be expecting Baldur's Gate II. Real time 2D battles, first person dungeons, top down RPG towns, it likes to play with a lot of styles. I love this game, personally.
Columns III: Revenge of the Columns: As if you care, Columns II was an arcade game. That's what happened to that. Columns III was kind of cool, but it's still Columns. Play Tetris Attack or Puyo Puyo 2.
Bio-Hazard Battle: The only horizontal shmup to take place in Racoon Ci... oh, wait. No. This is a pretty cool game. Nothing too special, but not bad. It's also two-player.
