Star Wars: Knights of the Old Republic
I finally completed the game! This is one of those games that I've tried over and over to get into ever since it was released on the XBOX. In fact, I got an XBOX specifically to play this game, though I never got very far into it back then. I think three things prevented me from getting anywhere in this game until recently: the interface/controls, the starting area, and the combat.
First, the interface is just awful. The game was clearly designed to be played with a controller in hand in the living room, and then awkwardly ported to keyboard and mouse (strangely, with controller support completely missing). I was able to put up with it, but it never felt comfortable; it is possible to give each character orders during combat, but it's a bizarre system involving pressing space to pause combat and then pressing TAB to switch to the next character and give an order.
Second, the starting area is very boring, and also very long. You run around a bunch of very similar looking and long hallways, picking up quests... which often involve crossing these many maps back and forth over and over. You then go to what is basically a boring sewer.
Third, combat is mostly brainless and easy, but there's so much of it. Having said that, this is only a minor problem for me because it serves the dual purposes of breaking up the exploration and dialog, and making you feel like a badass Jedi warrior. Besides, this isn't a game you play for the combat... it's to explore the worlds, interact with the characters, and soak in the Star Wars atmosphere.
However, it's worth pushing through all that, because the game becomes quite fascinating and addictive once you get through the first area and are allowed to explore the galaxy. There are several planets on which you can land, and there's a good variety of environments and some very interesting quests, with a good mix of combat and dialog. You also start picking up more companions, and it's fun to try them all out.
I ended up really enjoying this, even though I really don't care about Star Wars! It still looks decent today, with some great vistas as you explore the various planets.
