fortunatly all list are personal flavour and will never reflect all players alltime greatest. though ranking games of different genre's is senseless, imho.
even if i never played it civilisation is one of the absolute classics you will find it along with elite, simcity (which i rank much higher then sims, get's boring after a while, classic sc i still play sometimes). what about zelda? railroad tycoon (i miss the dispatching in later clones)? racing games (countless, my favorite; sports car gt, needs wheel and pedals to be played well), sport sims in general, hard to find a unbeaten one. boulder dash, galaga? (all clones included and "deluxe" foremost, a womens favorite as i know, played by all my girlfriends, even if they didn't liked cumputer games overall, it must by that shiny glittering stuff, i don't know), "kaiser" (c64). a very personal selection sim-earth (i wonder who else plays this game). if you like to loose the battle allways, play global effect. donkey kong & mario (snes) spend many h'rs with my family in front of. one you might never heard of, vectron, advanced dungeons & dragons it's a predator. lemmings, a classic which i never liked to much. i don't like war kind strategy games, or simple beat'em ups, maybe tiny troops (remember?). settlers, a must, especially the original amiga version (two players on one machine). populous, to go on, sadly you needet two machines linked to play together (no web those days) pc crap.
no not especially pc, to play some games together on one machine without ai is allways "easier" then otherwise (remember old inty, often no ai only p vs p, because of lack of cpu power and media size, even in strategy games such as utopia), they didn't do it to sell the games double simply, imo.
i nearly forgot, ports of call, play the amiga version emulated, the pc release is crap (and it shows off the levels of those days). two sega classics sonic and shinobi, some might utter golden axe (not me).
best selled is not very improving, maybe most copied (pirated) over a long timespan or the percentual amount of, would give a better result.
