If ya lookin for a decent old-timey western RPG series to play, I highly recommend the Ultima series. In fact, quite a few of the early games are free on GOG, and the latter ones (like VII, easily one of the best games of all time) are still pretty cheap, weighing in at around $6. Cheap, not graphically intensive in the slightest, and looooooots of play time, lemme yell ya. Hell, just Ultima IV will have you playing for at least a few weeks before you beat it, and that's even with a fair piece of foreknowledge.
