IT really is fun to play, VERY good game. Cant wait when its complete!
Personally, I am not getting any progress for months (game time), no further research possible. I have live aliens of all 4 sorts, 7 bases, can use particle weapons easily in tactical, have no idea where to get ammo for aircraft particle cannon (still have only the original aircraft weapons really usable), IR goggles have still no effect (or I misunderstand how to use it?) and I have two new aircraft (Dragon, Stingray). I have antimatter storage in all bases. This seems to me the actual game limit so far. I can shoot any UFO flying around, radar the whole atmosphere and win any tactical mission. Medium difficulty.
