For a free TBS type of game you guys could try Battle for Wesnoth.
I played Tactics Ogre for the 64 and I am waiting to see if Nintendo will be bringing it back to the Virtual Console(unless they already did).
The other TBS games I play are Civilization 3 and 4, gonna download that Free Vantage Masters to try it out.
Please keep mentioning other TBS games since they are the type of games I love.
Quick question: Can a TBS type game be done in rpg maker?(any version)
