I'm a hardcore when it comes to PES. but that's it. I don't play anything else. I love football see and that's why i love football games.
I consider hardcore gamers as those who play a whole variety of games, not just one or two like i do. If you get what i mean.
I consider my brother a hardcore gamer. Someone with his 360 who seems to buy this and that game every week. he has about a 100 games or so (i don't know how many). I just play one game. if it wasn't for PES or FIFA i wouldn't play games at all pretty much.
I mean i only found out the other day what overclocking meant.

Sorry I'm a complete 'noob' when i comes to gaming terms.
