Why not just make it turn based then?
I love turn based games, but there is definitely a different feel with a RTS that feels less ‘boardgamey’.
I know what OP means - ie StarCraft without the micro.
I have played it for almost 50 hours now and I don't feel you have to do things too quickly if you aren't aiming to be in the top 100. If you have already memorized your plan and responses, it becomes pretty slow and stress free.
