Same here. The last Nintendo console I owned was SNES. When I saw the N64, I felt sick to my stomach. Especially by what they did to my classic Mario and Zelda, turned them from lovable games with real character into ugly 3D crap. As far as I'm concerned, the Zelda series ended with Zelda 4 (Link's Awakening), any games after that don't count.
The ones that really made me rage were in Lufia 2. I actually like puzzle games, but I like RPGs more. When I'm heavy in RPG mode, cruising along, then get interrupted with a sliding blocks puzzle? RRRRRRRRRRRRRRAAAAAAAAAAAAAAAAGGGGGGGGGGGGEEEEEEEE EE!!!!!!!!!! Note to RPG developers: keep the non-RPG game elements in the mini-games, okay?
My personal sins? I've impersonated a female on MMOs, just for the free loot showered on me by stupid horny kids. I own a PS2, Dreamcast, Saturn, NES, Sega CD-X, and GBA, all with awesome games (and a Dingoo a320 for playing hacks and english patches for other games). What am I going to play when I get home tonight? 3DO. Gex, Need for Speed, The Incredible Machine, Twisted... ahh, fun. Maybe some Angry Birds too.
