I grabbed a two-pack of licenses while the game was on sale a few years ago, as my brother and I live across the country from each other and wanted a few more games in common in our libraries to play together. Honestly, I'd have paid the full $6 for the two-pack. For a basic tower defense game, this is pretty good. (Please note, I have not played
Cubemen 2.)
The game has several modes and modifiers for each of those modes. There's a basic tower defense mode, a skirmish mode and a mayhem mode. To date, I have limited experience with the skirmish and mayhem modes, as the online multiplayer is essentially dead, in my experience. The only time I get to play online these days is when my brother is actually online, and that's difficult for us to coordinate. Single-player tower defense is a blast, though. There's a wide array of maps, with user-created maps available for download. Unfortunately, I had trouble getting any of them to load. That said, you can customize player/team colors, views (top down or 3D), and play speed. They give you a decent selection of troops. At the end of each round, you're graded with a complete breakdown of what happened and awarded a medal indicating how you did (bronze, silver, gold and platinum).
The main downside is the achievements are difficult to 100% without boosting. At $3 a license, though, it shouldn't be too difficult to grab a few copies for friends and organize a game night. Otherwise, 40-50 hours of work (the "WARRIOR LEGEND" achievement is a major grind) can net you the 100% in single-player mode.
