[Multiplatform] Game Series you just stopped playing. Sonic is the correct answer, by the way.

I gave up on Quake after II. I played through Quake III and IV, but really didn't enjoy them that much.

Final Fantasy, X was it for me. X-2 and XII were so utterly unenjoyable in the little bits I tried (I own both but haven't played either for more than an hour) that I'm tired of it. I still like the classics - Technically I've only beat 6-10, so I'm playing 4 and 5 right now. But one of the main points for me is that if I want some goofy "realistic" battle system, I'll play, you know, an action game. I like turn-based combat in my RPGs, sorry.

Also, yet another vote for Pokemon. I loved red/blue. Everything like that has seemed like a cheap milk-the-cash-cow attempt, sort of like the entire Friday the 13th series.

Jam it back in, in the dark.
