Adventuring to Different Dimensions

If some of you may know, Yokasf can make dimensions where he could create worlds based in his imagination. So by using this concept, I was thinking that Yokasf could host tabletop rpgs in dimensions and other characters could enter and play around in the dimension while Yokasf is essentially the GM. I don't know what pen-and-paper rpg I should use right now, but I'm toying with the idea, if anyone is interested.

I could be interested, waiting for abit more detail for a better understanding.

I thought about this a little bit more, so here are my thoughts.

• Yokasf creates dimensions based on the following.
• From the list, others will choose from the list for Yokasf to replicate in his dimensions.
• There will be a time period where Yokasf will build the dimension. This is actually an excuse to research the choice. Time may vary.
• Once enough time has passed, a notice will be made for finding participants in joining a session.
• After a time period after two or more participants have signed up, a thread starting the session will be made in Yokasf's Room.
• Anyone can join at anytime, but only when it's possible to join without disrupting the flow.

Inside Dimensions

• Time works differently inside dimensions. Yokasf determines the time ratio in the dimension to real life. 
• Once inside, the participants will be subjected to the dimension's rules which may vary depending on the game.
• First time participants must make their character sheet for the dimension if applicable. This must happen before entering the dimension.
• A session will begin once the participants are ready. The length is dependent on separate parts.
• Death is non-existent in dimensions.
• Yokasf will be constantly monitoring the progress of the participants, and will force events in the dimension.
• Characters can still use their abilities, but depending on the dimension, Yokasf may alter the dimension to balance the play.
• Anyone can leave at any time as long the ask Yokasf to let them out.

And that's what I thought up so far, I will add to this over time.
