Well... I had 70+ NES games growing up. 30-40 Genisis/(mastersystem?) games, and various SNES and so forth's growing up. Playstation, gameboy, N64. Computer stuff...
Games are often cheaply made--crap, in other words.
I buy about 2 major (new) games a year, but sometimes have to buy two copies as my GF also plays games. We do get some arcade titles, and some computer stuff... but yeah... I research a lot before I buy.
As it is, other than Star Wars Old republic, I have no "new games" in mind right nwo that my old games can't do. As far as old games go, there's a lot to get there, still.
