Personally, I think everyone who loves the OT should give it a shot, because wheras the first game was almost completely about the prequels, this game is fully centered about the OT. True, there's actually stuff from the SE and the prequels in there, but overall, it's nice to see the comedic take on all three films.
Also, note that the game is silent. No one talks except for mumbling and the alien languages. In fact, for Vader to tell Luke he's his father, he pulls out a picture of him and Padme to prove it!
The game's not very hard. Even though you can die in the game, you have unlimited lives! You just lose studs (money to buy extras) when you do die. The only hard part is that it's easy to get stuck in the game's many puzzles, but eventually you'll figure them out.
But the biggest suprise of all is the Ewok celebration at the end of the game. They actually use the Yub Nug song. As much as the game centers around the SE (Hayden Anakin is the ghost BTW), they use an element from the OOT in there. Probably because it was released in conjunction with the OOT on DVD. It even has a preview of it on the disc.
Also, you can create your own characters in the game to use in free play mode. You can even play as prequel characters in the OT! (Provided you have a save file for the first game on your memory card.)
Overall, this is a terrific and challenging game for kids and adults. It's not terribly frustrating and people have a chance to beat it. Everyone can forget about Super Star Wars now. This is the definitive OT game. (That is until Star Wars 2007 the game comes out...)
