TL;DR Warning!!
Spiral Knights is an amazing game, a revolution in MMORPGs in it's own right, it's cute, it's casual, it's easy. There are no complicated skill trees, no large confusing maps, the game is designed to make it quick and easy to find some friends and get into the action. While normally a game like this would consume most of my life, I can't bring myself to play the game for very long, litterally, after your energy runs out you can't play the game. It just becomes a big 3D chatroom, like a chibi Second Life. Spiral Knights reminds me of a facebook game, you know, the one that lets you play for an hour or two and then makes you wait till tommorow to play again, while this is a great way to get your customer to keep coming back to your game, it also becomes annoying if you really enjoy playing the game.
My last gripe with the game is the Arcade, while the idea is great on paper, in practice it all falls apart. While it's great to have players create there own dungeons, to keep things fresh and new, the system fails to do that, most dungeons are the same level repeated, i've played in a dungeon were the first four floors were the EXACT same level. Having hundreds of players constantly spamming minerals into a gate to get crowns means that gates aren't really player created, there just random. You can't organize hundreds of people, there's always going to be a handful of people who don't listen.
All that aside, Spiral Knights is probably the first "causal" MMORPG iv'e seen in my life, I'm sure I show this game to anyone and they could pick up on it very quickly, it's a great game that removes the stress of most major RPGs, no hotkeys to memorize, no stat points. To a guy like me who can easily become overwhelmed by those kind of things, this game is a nice relief. Did I mention it's really cute?
any armor above that is higher than 2 or 3 stars requires an amount of energy that no normal playing could achive without paying for it
