Can Turn Watcher™ be used with any d20 game?

Yes.

Turn Watcher™ was designed for the d20 rules and the initiative and combat rules of all the d20 games, Dungeons & Dragons or Modern or any other time frame will all work just fine.

Of course... The website looks quite heroic fantasy. That's just because that's what we like best.

Icons

It would be cool to be able to change the icons or theme... say to a horror game for example.
