ITT: Graphics are important, and Bulletwitch was a terrible game. But so was RE. and so was Halo 2 and 3. and so was... oh nevermind <_<
It's not about "Gaming purity", as it was so WW2ly put, it's about the quality of content. Being able to ask yourself if you accomplished something while playing (you know, outside of doing something productive like riding a bike irl or something). Did you get to that 9th level of metroid? (olo Jarhead quote; I know theres no 9th level.) Did you play Bubble Bobble until you reached level 99???? Did you get every weapon in the game??? etc
