Why not work on Guild Wars? There is a system that at one point in time was amazingly fun!
This assertion can be used to describe what we are aiming for with regard to how Virtue and Vice will work out. You won't have to wait for a certain time for a battle to begin, it will be based on population. What I mean by that is, so long as there are a requisite number of opponents the matches will begin automatically and continue so long as the population requirement is met. You won't have to say, wait for a match to begin at 7pm. Not the case at all! Instead the system will monitor login/logoff activities and so long as two opposing guilds are online a match will start and continue with brief cooldowns in between. Matches will be objective based with short match timers - probably aiming around 20 minutes or until a score threshold is met, with about a 5 minute cooldown in between. Of course this is subject to change based on future play testing, but it gives you and idea of what we are aiming for in terms of flow.
