In the end, this game was slightly disappointing
For one thing, Lucas Arts didn't improve the game in terms of graphics or storyline. The only changes made were the new factions, campaigns and units (and some of the more insanely powerful ones were a lot of fun to play with).
I also think that Lucas Arts should have waited for episode 3 because that is when fighters from both sides are introduced, since the republic laat/i would not be used as a fighter and would be better suited as a transport.
Worth mentioning though, is the map editor mode in which you can create your own scenarios. This is where you will find most of the fun once you have finished the campaign
The game is still good, since it still has the essential formula that made up galactic battlegrounds, but the fact that they haven't changed that formula is where the game fails.
