Be careful with XCOM2 if you like strategy games... I lost many weekends to that game in college. The expansion pack (War of the Chosen) is well worth the money. Honestly just talking about it now is making me want to reinstall it. I like that game so much that I've actually bought it twice.

You gotta play xcom:ew long war mod. It's amazingly deep and different (and difficult). But the game play is a lot more intense and engaging.
