Yeah, Brain Training is the PAL name for Brain Age, just a force of habit on my part.

Just replace Pokemon G/S on my GB list with Metroid 2 and replace Pokemon Crystal on my GBC list with Pokemon G/S.

Thanks

wasn't that for the Gamecube?

*sighs* You would be correct, lemme go edit that. It's probably because I was starting to think of the GC games while doing the N64... multitasking is not a good thing at times...

Could you expand these lists up to 5 games? As for The Last Guardian, it's unreleased so I can't really include it. We don't know how impactful this gam will be released, and realistically there is a small chance the game gets cancelled or delayed (like Duke Nukem). Also most people made lists which don't include upcoming games.

I can't include unreleased 3DS games, but maybe down the road I'll make this thread again and see how opinions change over time.

Good Job inclding Game Gear, I completly forgot about that console myself, and I'll cast my vote for it later.

Also, what's the difference between Sega Master System and the Genesis? I know they are different, but as the Master Sstem even released outside of Japan?

Fair enough on the 3DS, it's why I flagged it as tentative. I could even do more systems, but I really would have to think on them. (First one I'd get to would be the TG-16, which would be Bonk's Adventure and Ys I, but then I'd really have to think...)

As for the difference between Master System and Genesis, it's... rather large. The Master System was Sega's attempt to compete with Nintendo. Released in 1986 in the Americas, it really didn't catch on here. It did fare better in Japan and Europe, where Nintendo hadn't been seen as resurrecting a market to get a sudden stranglehold. It was also the system that let Sega get a strong base in South America. Technically, it was an 8-bit system with more RAM and better sound outputs than the NES.

The Genesis (or Mega Drive, if you prefer), launched in 1989 in America, well... a lot more is known about. I don't think I need to go into detail on this one...

Splatterhouse should be inclded for TG-16.

Master System probably didn't sell well because it also only had a 3 ear life span. BTW Sonic the Hedgehog for Master System, was that a downgraded port released when the Genesis version was released?
