ok, i have several qualms about the new list; here are a few-
1. while it is streamlined, there is no allowance for post-episode VI units- the likes of which would be necessary in any YV mod. What we could do is, like Varlin suggested, add the YV mod as a sort of 'expansion pack' and include in that expansion pack an era 5 for the Rebel Alliance to include such units as the New Republic Star Destroyer and the Bulwark Battlecruiser so as to allow for accurate YV Invasion-era combat. I could settle for that, and postpone making the New Republic-era units for the expansion pack.
2. many upgrades don't make sense such as TIE Interceptor>TIE Advanced; the TIE Interceptor came after the TIE Advanced and (i think) was more powerful and able to be mass-produced. Why would the Sith Interceptor, possibly the most powerful one-man ship in the galaxy, upgrade to a simple Belbullab-22 Fighter? etc etc etc
3. I structured my unit tree so that:
-Era 1 represented episode I for the Republic and CIS (though it technically didn't exist until episode II) and episode IV for the Rebels and Empire
-Era 2 represented episode II for the Republic and CIS and V for the Rebels and Empire
-Era 3 represented the inbetween (clone wars) for the Republic and CIS and Episode VI for the Empire
-Era 4 represented episode III for the Republic and CIS and post-VI for Empire and Rebels.
i liked the way it was structured to follow the episodes, but the new tree lacks that- the geonosian warrior can be built in era 1 while the Droid Control ship can't until era 2, etc.
4. this is not a qualm, but i noticed this in Chris's and Sheepmonster's unit trees- that they have light cruisers, star cruisers, and flagship units. As a compromise, i could rearrange the tree to allow for flagship units
5. We could have the empire have 'gun tower,' but i couldn't find any turrets for them and seeing as they have powerful mechs i figure to balance that out the Empire could lack turrets.
6. To save unit-graphics-making time, it could be possible for there to be a single bounty hunter graphic, prefarably Boba Fett (since he is the supreme bounty hunter and is the clone of the Jango Fett of the prequels, resembling him).
7. I can't upload Unit Tree 6 and Unit List 2- they don't show up in the uploads folder- i'll try to find out what's wrong, so expect them soon.
