This looks good. Not great.
I only read the top response and I've got ideas for the game. That's generally a bad thing. I do have ideas though so i guess there's that.
Create a scoreboard. Chess rules. Tournaments. Prizes. All under the name of "competition" between FPS players and chess players OR FPS players and RTS players (same third-person view dynamic). My company could pair you up with an analytics company to keep the scoreboards accurate and the press rolling.
Let me know if you're interested.
It's a good game but it needs a much shorter introduction and the very first time you play it, it should be way easier.
Good graphics. Excellent animation. Repetitive music. Short gameplayability.
Needs more kick in the start!
