I think this title belongs to the original DooM! Before that, games were blocky little aliens zooming about the screen being shot at by another little blocky thing. Just go back and see what the original DooM does have. Check out those mountain scenes through the windows. Can't see where the walls join like is REDICULOUSLY obvious in some levels of undying. DooM was such a leap ahead in gaming that it stunned people waaay back when. Try the new JDooM mod incidentally, accelerated graphics in DooM are certainly worth a look.
