Just added Dragon Sphere to my list http://www.gog.com/forum/general/games_finished_in_2013/post107
If anyone has never bothered to add it to their shelves and give it a go (its one of the free ones on here) then I'll tell you that its a strange old point and click adventure that's incredibly fair - you automatically rewind after every death and it goes out of its way to make sure you don't end up in an unwinable state
Its a bit light on hints though and a one point a character gives you detailed information you might not realise you need and then never repeats it - just says "I have already told you all that I know' or something, although I'd already done the puzzle in question by trial and error at that point anyway!
There's something really old and hoakey about the whole thing though, and i don't mean because its from 1994 - it feels more like its from 1954, like watching something staring Errol Flynn on a rainy Sunday afternoon, the fact that all the old-timey sounding voice acting sounds like it was recorded in a cave doesn't help either!
But all in all a fairly good diversion for free - which is always a good price-point!
