So many Amigoids idea of good gameplay seems to entail simplistic platformers or shooters; frankly I have no patience for the zillionth 32 color Mario-alike. Games for me either have to have technical depth (flight sims) or a rich story (RPGs, like the SSI gold box games and others), or elements of both; the nightmarish sci-fi background of the Half Life universe is a good example of this.
"Oh," many of you decry, "it is another boring PC FPS." - yes, because it's on the PC. If by some miracle Valve allowed it to be ported to other systems and a build was released for the Amiga, I know the game would be embraced by the same detractors.
Game "play", anyway, is a vague and indistinct concept. Yes, you might (wrongly) think that there's no difference between, say, Doom and the System Shock games (to go all retro on you) but utterly depthless sprite-hoppers like the SotB series, The Killing Gameshow, etc. etc. - those are the same games with different sprites, fact.
