It would be great if they somehow added in RT4X features that Sins of a Solar Empire had (read: more tactics, ship HP carrying over, multiple battles at same time, more interactive tech tree, scalability, fix the stupid CTD (UaW had SOOO MANY of these...and my PC is only 1&1/2 years old! If you're going to tell me to get a new computer (that is vista, shudders), then you're shutting out a huge percentage of computer users. FoC didn't crash as much (or at all) as UaW), NO gfw:live, ADD in diplomacy/small factions, mutiny in empire, etc.) and made land more fun (read: carry over things from UaW, or better yet, scrap land in its current form to allow RT battles and empire management as in SoSE and come up with a new method somehow. I never got how a conclusion on a small battlefield on a entire planet decided how that planets affiliation would be. Or why my space units couldn't help more on land (or if a mod did, how to solve scaling issues, and engine pathing issues))
Lucasarts should make games in house, I mean, IL&M has so good quality models they made for the movies. If they just took those models and instead of going from the ground up, scaled them down in quality so the average user could run it and strapped it to a good (efficient) engine, that would be a GREAT game! Would save the time of creating the game models, so they can focus on game mechanics, map design (or maybe use the movies ones), features, etc.
