While Enemy Unknown is pretty good, what I hate about it is you only get the one dropship. Xenonauts however is just like UFO Defense in that you can have as many as you want. I generally get another dropship at the start, which allows me to deal with more crashsites at once early on and it allows me to quickly build up a lot of experienced soldiers. It helps me later on in case my primary team manages to get turned into Alien Stew.

Another benefit is the ability to make multiple bases. I'll setup a base to cover solely on R&D and another for Production, with yet another solely for Intercept.

Now, if ONLY there was a multiplayer setup for it. Can you guys imagine if you have 2-4 players doing a go? With 4 players, one can concentrate on R&D, another on Production, with a 3rd doing Intercept and the last person doing the ground pounding.

Would be tough early one but once they have things smoothed out, oh yeah!
