All of them… for years. Do you know what influence means? Of course D3’s primary influence is D2; but I’m also sure that the developers have played more than just D2 and have taken things from them. Oh well, I just saying what watching the game made me feel like. If you don’t feel it, then you don’t.
I think you can D2 and LoD for like $30 in the Battlechest. Or you can get copies of the game a buy a key for like $5. I wouldn’t even bother with Diablo 1 anyway.
I think the thread title should be changed from “Diablo 3?!” to “Diablo 3!!!”
Also, about this games reqs, I’m not worrying too much. Blizzard has always been really good with delivering great looking games that don’t have high system reqs.
