I don't quest, but I don't like the rtb questing system in general. On games where I quest, I like quest that are found in the environment. I.e. you are walking along in the woods, and you find a talking rabbit.
SS2 is pc dos...simple graphics as it gets, but the strat and cat and mouse play are still awesome. SH3 is the next best thing and for its time the graphics are primo.
