What about the ST keeps you coming back then?
I think it's great that it keeps you going back. Yes there will be parts of nostalgia and a fair amount of rose tinted specs in there too but if you are happy who cares?
As for playing inferior version of a game? I do that more than I used to unless it is a poor version. I always used to look for the best version I could play but now as long as the game is playable I'm not so bothered.
