We have been talking about making a "lore accurate" version of X-Wing, where we would replace some ships with the ones that were actually used in the lore.
Not only GR-75 Medium transports would replace the bulk freighters for rebels.

Imperials should use:
- Arquitens cruisers instead of Nebulon-B frigates.
- Raider-class corvettes instead of CR-90 corellian corvettes. Or at least Gozanti-class assault transports.
- Sentinel-class shuttles instead of Stormtrooper transports (although the stormtrooper transport has appeared in some canon source, but its use is extremely rare).
- TIE Advenced Prototypes (TIE v1), or TIE Defenders (TIE x7), instead of multiples of Darth Vader's TIE x1.

Rebels should use:
- U-wings instead of stormtrooper transports or lambda-class shuttles (although it might make sense for them to use stolen shuttles now and then).
- GR-75 medium transports instead of bulk freighters.

However, all these changes would make the game feel quite different and break the balance of the original misisons.
So it is better to have this as a later, optional mod, instead of built-in.
I think Unity can only handle up to 20 buttons per controller.
But sure, we will have a chance to test all of this once we release the demo.
