How does it work if members of your party only have the base game, and others have Titans? Are these two separate games? Or does co-op work between the versions and permit Titans to smash my non Titan forces?
If you own Titans you can switch between Titans and Classic mode (in the Settings menu). While in Classic mode you can play with others who only have the base game.
One thought for a possible update (sorry I know you've only just launched it!)... maybe an improvement on that would be to allow Titans players to see all games in the multi player lobby (with a filter I guess and something in the UI to identify classic games) without needing to switch in the settings? Or is it a case of having to relaunch the game? Also I notice, recommended 12gb or ram? Edit: Just some thoughts, Titans looks awesome either way
