The degree of difficulty on this one wasn’t very high, but GameSpot editor Greg Kasavin gets points for nice execution: Real life: The full review.
Unlike in other MMORPGs, combat actually isn’t a major factor for most players in real life, though players are bound to engage in a few skirmishes early in their lives. Interestingly, though, real life does offer an amazingly intricate combat system, featuring complex hand-to-hand and ranged combat options that a character may learn and even specialize in. Combat-oriented characters lead exciting but sometimes short lives in real life.
That being the case, you’d think more players would be drawn to combat in real life, and in some territories, they are. However, the PVE (player vs. environment) aspect of real life is relatively unpopular, and the PVP (player vs. player) portion, while interesting, is far too risky for most of the population. That’s on account of the game’s very strict death penalty and punitive system–you may freely attempt to harm or kill any other player at any time, but you will then likely be heavily punished by the game’s player-run authorities.
