I'm not keen on the PS1 versions of these games; they have pretty significant load times bordering on unbearable, but they're still the best versions of V and VI on sale right now (the Android/iOS versions have really bad DRM to the point that I cannot in good conscience recommend them, and the GBA versions are sadly discontinued and rather expensive). As for I and II, the PSP versions are far and away the best versions out there, and can still be had new for fairly cheap, albeit not quite this cheap.
