1. Real time combat - Much like Browser Quest where you walk up to creatures and fight them and they fight you, chase you ect...
2. Final Fantasy like combat - Creatures still roam the map but when you touch them you go into a separate combat screen

It is not a question of difficulty. Either one is feasible and with multiplayer. The party system I have planned will allow multiple players to battle at once using option 2.
What is everyone's opinions?
