User blog comment:ChishioKunrin/How much work would go into a RWBY MMO?/@comment-25555436-20150911180756

...Just wondering, what do you mean exactly: MMO, or MMORPG? And if so, of what kind?

An MMO just needs to be online and gather many, many players. In everything else, it varies greatly.

Second Life is about, well, giving up your life in exchange for a virtual one where you are not necesarily a loser or anything, instead being the badass Mr. Muscles you know you are not. It's an MMO.

Warframe is about being a space alien ninja, performing missions in pre-made, randomly-arranged areas of a specific type until you finish the mission. It's an MMO.

Elsword uses 2.5D gameplay with a bigger focus in combat, having a more combo-focused system that gears more towards performing different combos and possibly combine them with some skill. Players mostly play in "dungeons" where you beat every enemy in a room before moving to the next, until defeating the boss. It's an MMORPG.

Guild Wars 2 has a huge world to explore with maaany players around (except in medium-level areas) and adds some spice with the game having an actual story supposedly based to a point in one's personal decisions, although your decisions only affect your story, not everyone else's. It's an MMORPG.
