Well, I must agree with both of you guys on this topic. It could have been MUCH better and there were lots of things wrong with it, like Superfly said. On the other hand, I enjoyed it probably because I am a hardcore Star Wars fan. It was too short however, but I enjoy playing a good versus match every now and then. I give it a 7/10...
Lord Of The Rings was boring and repetitive like you said, and I personally considerred that game to be a truly average game. Now considerring Episode III is inferioir in every way to the LOTR hack/slash games I think that means Ep III is way below average, and considerring the likes of Ninja Turtles, Golden Axe and Double Dragon were doing this sort of stuff almost two decades ago (and considerring I played these games merely days ago and they all brought a smile to my face) shows how much of a failure Episode III is.
The sad part is, people just see Star Wars and think it's worth buying. It is quite possibly the worst scrolling beat'em-up I have played in a long time. I approached the game because of the Star Wars license. I HAD to play the movie. I'm a huge Star Wars fan, but seeing as it only loosely followed the plot, and the graphics were sor murky and drab, that meant I had to rely on the gameplay to make it feel like Star Wars, because it certainly doesn't look like the striking pinnacle of special effects that the movies are. Strip away the license and you have an unfinished, boring, repetitive, buggy and pointless game.
Imagine if God Of War played like this game. It wouldn't sell a single unit.
