Its not all about graphics, it never has been.I totally agree, gameplay trumps all.
D2 is awesome, d3 is the biggest letdown of the year ( heck last 5 years ). Thats not nostalgia, i was 24 when d2 came out, i remember it well. Poe > d3.
My recent games i have replayed are fallout 2, planescape torment, systemshock 2, dungeon siege 2 and wizardry 7. I couldnt care less about the graphics.
Now, with that being said, since i play alot of games for many hours, why wouldnt i want the best computer money can buy ( so to speak )?
Would you rather play skyrim on a toaster with everything turned down, running like crap, all choppy and laggy or would you rather play it on ultra where the game runs like a dream and it it nice to look at to boot??
