Ixamyakxim: Did you ever play and enjoy the original XCOM? I'm most likely pulling the trigger on Xeno but I haven't looked at gameplay beyond the video here, and the reviews / comments.
I'm curious because if you never played XCOM, I won't worry too much about you thinking it's slow... but if you played and loved XCOM I might have to take a look at a few gameplay videos myself...!
Just my oppinion, but when you played and loved the original X-Com game (especially Ufo Defense and Terror from the Deep), you should give Xenonauts a try.
Regarding the gameplay it's very similar to the old games. They changed some things (like the equipment management, the ability to use alien technology or the interceptor combat), but overall it's a worthy successor. And if you even want it to be more similar to the old games, you can use some of the community mods.
