there is no denying they are quality games but...they are not mandatory overall.
well, maaaaaybe diablo if only for some of the quotes. same for starcraft i guess >_>;;
the actual gameplay...eh...i never was a hugs fan of rts, so never got into starcraft's gameplay despite it being awesome. diablo is a bit dated now and if you want an example of its gameplay evolved some, look up torchlight.
good games, but i would put civ 2 above them.
