Tutorial is highly unlikely as a playable version. A video maybe.... ingame, don't think so.

Beggars canyon could always be fun. I think JayBiggs suggested I have a go at creating it but I am occupied atm with another map.

Taun Tauns as a vehicle, probably not, they weren't used during battle as far as I know. Doesn't make much sense to me to have them running around underneath ATATs.

Hmmmmmm?

And Suriander your training ground proposal sounds an awful lot like the training mission in the Rogue Squadron games. Well identical pretty much. What was also nice about that map was that depending on what time of day you were playing it would effect the map. So play it in the evening and it was Tatooine at night, play it during the day it was a daylight map, and early in the morning or early evening you got a dusk or dawn map, a very nice touch which made the map feel completely different.

That was the original design for the Tauntauns as drawn by Ralph McQuarrie mate.

As for Tauntauns in game it is unlikely, but if we could have them it wouldn't be silly at all, you'd use them for recon/scouting, you'd have a much lower profile than if you were using a vehicle, and also you'd get there a lot quicker than on foot.
