In many ways the third and the tales games are very different to the first two, so perhaps give one of them a shot.
And BTW, I wouldn't look down at you at all, if you couldn't get into Monkey Island games. Well, I can't really anyways, due to the fact I still have a lot of catching up to do myself, but yeah, I imagine if I didn't have this catching up to do, I wouldn't because at least you are into some of the other classics.
