Bubsy in Claws Encounters of the Furred Kind - GenesisWould you believe I used to be good at this game as a kid? Seriously, I was capable of turning it on and beating it, no problem. Even though its been years, I was genuinely surprised how much it kicked my ass this time. Also, it pisses me off a lot more now than it did then. I can't say anything about Bubsy that hasn't already been said really, but I've always thought that there was a good game underneath the sharp edges, and I still believe it.
Sonic the Hedgehog 3 - GenesisA favorite that I can beat in my sleep. I finished it with all character combinations and all emeralds, so there would at least be a time commitment for the challenge. Probably my favorite Sonic game and it never, ever gets old.
Crystal's Pony Tale - GenesisDon't bust my chops for it.

I saw it on the unbeaten list, fired it up on the emulator to check it out, and less than half an hour later I'd beaten it. You don't play Sega Club games for their difficulty though. Its an adventure game of sorts. You wander around the levels collecting keys and items and solving "puzzles" that help you rescue the other ponies. Other than fighting the same "boss" a few times, that's all there is to it, and there's nothing bad about it other than it being a bit slow and choppy.
NHL '98 - GenesisThe Avs won the Stanley Cup. All I can say is its fucking fun. Who can argue with quality hockey? I like the faster pace of this game compared to its predecessors.
The Death and Return of Superman - GenesisAnother childhood favorite. I usually end up using one continue to beat this game. I thought I'd get away without it this time, but failed at the last second against the final boss. Still, that's much better than the usual point I use a continue. Still love this game.
Taz in Escape From Mars - GenesisI never beat this as a kid, and I've owned it for years as an adult without ever trying to finish it. Finally took care of business. The last level before the final boss is kind of a pain in the ass, but its a good fun platformer overall with some good variety.
Shui Hu: Feng Yun Zhuan - MegadriveSnagged this on ebay for cheap (its certainly one of the copy versions, but I really just wanted to play it on real hardware). Very cool beat 'em up, if a tad bit repetitive. Sometimes the number of enemies they throw at you is just ridiculous, but then overcoming that sort of thing is part of the fun.
