black mirror and phantasmagoria 2 are great! the former is like nibiru, only better and the latter is not really like the first phantasmagoria apart from both being interactive movies, but it's still very good! and you really should give a shot to sanitarium! apart from the annoying arcade parts (that you can try solving as long as you have to) it's brilliant. same goes for the longest journey and it doesn't even have arcade parts
and besides, adventure gamers shouldn't be so keen on graphics
