Need for Speed Most Wanted.
Underground 2 still looks great imo, Most Wanted looks quite rubbish
.
GTA3 and Vice city ( SA still has a bit more details).
Tbh, I think most strategy games have aged well, I have no problems with how games like Age of Empires 2, RA and RA2, Civilization, Settlers 3&4, Pharaoh, etc look.
Side platformers look fine too imho, Pricne of Persia, Commander Keen 4, etc, still look fine imho.
Medal of Honor Allied Assault, Battlefield 1942 have aged badly
. Forcing Anti alias makes it a bit better @ BF1942 but still not great.
Mafia, in the rural area's looks funny, the city area has aged too but doesn't look ''that'' bad yet, but the rural area's really look rubbish for these days haha.
Far Cry looks quite bad, only the water is still ''very nice'' , but the draw distance is, well erm appalling.
Star Trek Bridge Commander, especially the people look appalling, ships look okay ish and modded ships look great, but the officers/npc's/etc look absolute rubbish.
