A game can be great without someone liking it. For example, I don't like Gran Turismo 3 but that doesn't mean it's not a great game in its genre. Same goes for KOTOR and Morrowind.
When I say western rpg, I mean the ones that are huge and nonlinear and are made by companies not based in Japan. KOTOR and Morrowind were both so massive it would have taken me a lot more time than I was willing to put in to get the most enjoyment out of them. Most people like having a lot of options, but I'm weird and I don't. I like the linear, turn-based Japanese rpgs like Final Fantasy, where you have some freedom (like going on sidequests) but ultimately in the end you're always going to end up going to the same places every time you play. I also prefer menu-based and turn-based battle systems over real-time battle. Tales of Symphonia is probably the only exception, but even that, when you go into a battle, it takes you to a separate screen, which is how I like it.
As for Baldur's Gate and D&D, those are action-rpgs, which is a totally different thing. They are really more of a hack-n-slash than true rpgs.
