It also depends on what kind of roleplaying you like. For example, I really don't enjoy military roleplays. I prefer diplomacy roleplays and nation building. So you can give me a diplomatic crisis and I'll be very engaged, but turn it into a war and I'll quickly get bored and stop roleplaying about the status of my troops.

That's actually why I ICly said Resentine had command of the Kringalian forces invading Sporaltryus.
