If you get past a 100 hours in XCOM and you start to play the game with serious mods (Long War for example) and serious gameplay knowledge (ex: activation ranges in the first game, ambush exploits in the second), the game becomes really fun. Sure, it makes it super tryhard every minute along the way, but then you can REALLY feel like saving Earth. I finished both games, with both DLCs, each with and without Long War (8 runs in total), plus a few Impossible Ironman runs in the first game. I still have PTSD after those goddamn Meld canisters... but hey, neither of them are as hard as playing Xenonauts on Veteran mode!
