No, play one at a time to you get to a good scene,then the next and the next. You have the other games on pause in the task bar. So you can play several scenes one by one when you are ready.
I play 1 game, the others is running in the background. When I get to a scene, i play next game. Then when I`m ready i play through the scenes one by one.
Right now I`m playing: Corrupted love, Maid to Please, LSS, Freeloading family, Family Affair, SSP, Room for rent (again), Promises, DP, Fake Father and CRUSH college.
