This game has a great RTS focus and it's executed superbly well. The campaign is set up in a way where there is so much variety and a very satisfying sense of progression with each mission you complete, which can all be replay-able. On top of that there is a Skirmish mode which gives you that endless replay-ability, allowing you to customise exactly how you want to play. This is like the Age of Empires 2 of RTS ant games, it reigns supreme so far. If you're looking for a great sim/RTS with a theme on ants that lets you do what ants do, pick this up for sure!
