XCOM:EU was great. The enemy spawning was certainly an annoyance but not a major issue in the grand scheme of things. Personally I think the decision to allow saving in-mission was a mistake, as it makes it too easy to save-scum - it devalued the strategy map and the consequences for failure.
As for this game, at least they seem to have recognised the game was on the wrong track and hopefully the new direction will be an improvement. We'll see.
