I love the concept of this game, and I will definitely think on is as I've aspired to make time travel meta games.
I can see eRe4s3r's point of view though, the only real battlefield is the past - the further back the better. (Why would you spend resources to travel into the future and build an army in the future?)
There is a limit on the number of orders you can issue in the past, but that seems to be a broken mechanic because then the meta-game becomes accomplishing the most through the fewest orders possible. "I could strategically flank them, but that would be too many orders so I'll just issue a single move command into the middle of the enemies base and hope for the best."
Brilliant idea though. Hopefully the developer hasn't stretched himself too thin.
In the FAQ it sates: "we are considering using or licencing this technology for other types of games including casual, core, serious, and online."
You can't license a game mechanic can you? That'd be like someone licensing the FPS genre. Some stupid licenses have been granted in the past though, and to further complicate things having a licenses (patent) doesn't necessarily mean it's valid and will hold up in court.
