Hello, Thanks for the replies. My comments are below.

I.e. I could not use that to reverse time and then start playing the game again (with a different future) from that earlier point in time. The replay I wish to do will only be up to around 20sec in the past. The optimal result would be to have features of time manipulation like those found in the 2D game Braid: http://braid-game.com/news/ However i realise that much of Braid is possible because it is a simple 2D game, and hence my idea of prototyping in 3D to see how feasible it will be to have time manipulation in a 3D game. I have a short summary of the time manipulation features i think would be good to try and implement in this prototype. I would like to try and do it the simple way first just saving into memory all game state at regular intervals maybe every 500ms, however i am currently not sure exactly how much data that would be and also how long it takes to save the game state for a particular sector and surrounding sectors in CEL for an average RPG. It could get large quickly I imagine and the figures probably vary a lot depending on the game. In which case there are a number of optimisations that could be applied like keyframing + deltas etc. But before i get there i guess i should look at making a "simple" game in C++ using CEL Thanks for the info. I think i will subscribe to the CEL list and look at bit more into creating a simple game first.
