Stick Empires, is the multiplayer sequel to Stick War II: Order Empire, if you have ever played it. If you haven't, it is a 2.5d rts with all that entails, make units, grow economy, destroy enemy base. Resources are obtained from resource nodes or the capture point in the middle of the map to prevent a permanent stalemate.
What makes Stick Empires so unique are the different factions that the game has. I think back in the day you had to pay for a membership to play any faction other then Order but now that is not the case. Order is your kind of standard human good faction, with a unit for each archetype, like flying, stealth, etc. Chaos acts as a more aggressive counterpart to Order, with slightly cheaper units at the cost of health. Meanwhile the Elementals are extremely interesting, with 4 "basic" units that can fuse with each other to create more specialized forms. This ends up having some pretty interesting back and forth once you add upgrades into the mix. The games are pretty quick, being about 20 minutes or faster depending how hard the steamroll goes.
The game modes in stick empires are bog standard, with a normal match, and "Death Match", which is just a normal match except with bonus gold and mana for both players. There is also bot matches if there is no one to play with you. It has a decent friend list system to have private matches with.

Overall, I think this is one of the best flash games I've played, and a decent RTS game in general. I'll put a guide at the end of the review so you can check it out you want to.
