The Battlefront series- why not on Gamecube?

Okay, yes, I know I haven't added to the 100 games thing, but I've been very busy. I've been working down at my mom's print shop. $2 an hour for shredding paper. Do you make that much? I don't think so. Okay, now, I'm here to discuss a topic that's been bugging me for a bit. Why wasn't a single Star Wars: Battlefront game released on Gamecube? At first, I thought it was because the Battlefront series is really about online multiplayer, but then I remembered, the GC did online. And maybe if they had a really cool and popular online game on Gamecube, it would of been way better :P. Then I considered maybe there was a storage issue or something. According to Wikipedia, a GC game disc is 1.5 GB. This is way smaller than PS2 discs and Xbox discs. They were 8.5 GBs on average. According to Wikipedia, the PC version of Battlefront II is 1.67 GBs, but I'm sure that they could of done some compressing or stuff. So, really, why didn't they make a Battlefront game for GC? I mean, it would of worked. Now, really, why didn't they? Nowadays, I really wish they would at least port it to Wii. I mean, it would work. Heck, they could probably put both of them on a Wii disc. And with online multiplayer, it'd be perfect. Basically, I just want a new Battlefront game. Let it be III, a remake, a port, or something along the lines like Renegade or Elite Squadron. A port would probably be best. Just don't mess with anything, and it'll be good.
