I think both The Force Unleased and The Force Unleashed II would look good enough to play. There are likely textures and mods out there for them too, although I haven't checked.
They are both a different gameplay experience from JFO though, so both have something to offer if you like the styles. JFO is really more Tomb Raider style in the Star Wars setting; lots of running, jumping, climbing, and puzzles. It can get a bit tiresome I thought and I just wanted to be a Jedi damn it! Some puzzles don't make sense, I might have mentioned that, like I can't cut something with my lightsaber but I can burn it with fire...?! But I am still glad to have played it, mostly...

The other two are more traditional games of the action style, and I think you have more force powers too iirc.
@sswilson it wasn't all in one sitting, but yeah, I would say nearly 3 hrs. There were two other boss battles that took me a couple hrs too I'd say. The game isn't easy, or it wasn't for me anyway lol
@lowfat I'm glad it wasn't just me then! My daughter was laughing at the tirade I would go on each time I died! lol It was a pretty good ending though, no spoilers, so I'm glad I made it.
