tekken, soul cal, and virtua fighter are good games... but i just like the simple games with SHORT move lists. Although every direction combined with a buttion does a move... I'm the kind of person who'd want to learn all moves and not just stick with a handful and focus my fighting style from those moves. I like street fighter style and crossovers and smash bros because you can just pick it up and just go at it. Although people who are already used to the many many moves on one character and in certain stances/position in the ring shouldn't have a problem. I bet a lotta ppl will be happy with the Street Fighter II games on the next gen systems if they have online play.
Like said earlier.. my friends also said SC3 was broken and that they didn't really 'enjoy' the Create a Character option. I dunno why off the top of my head tho. They mostly 'studied' Sophitia in SC3 on ps2 because her moves were broken or something I forget, but I think they fixed it when they released SC3 for the arcade, because i know they were complaining about how they changed one of her moves.
I think the most simple of Tekken, SC, and Virtua Fighter is SC, then tekken, then Virtua Fighter. This is just based on tournament videos though... so i don't have much to back it up on. If Smash Bros, a Virtua Fighter, Tekken 6, and Soul Calibur all come out at the same time... I wonder who'd 'prevail?'
