Already did Chaos OT, it lasted about a month. The crazy bots for tibia these days make ot chaos quite trivial... it would take some serious effort to enforce a no botting rule to keep ot chaos fair in all honesty. When I put it online, within that month people were roughly level 30k. I might add at that time it was an exact replica of ot chaos as far as exp rate, spawns, character strength. The only difference was the client being 8.6 rather than 7.6. I think chaos would either have to be on OTC or updated to the most recent tibia version, with many GMs checking people for bots all day.
