Can A Web Based Game Be Made?

[se5a]

I was thinking something like this but using the SE4 engine.
if yoiu could make engines have a decimal speed it would work....

basicly I thouhgt if yoiu made everything move realy slow you could have the turns tick over twice a day and it wouldent matter if you missed a turn or three (unless somone sent you a message)
so every 4 or 5 turns were equivilent of 1 normal game month.
maybe aaron could make somehting like this possable for SEV?
