Server Side - PvP or PvE
You can decide if you want to play like you normally should (PvP), or be a care bear pussy bitch. Don't be a fucking care bear.
Character Creator - Hero v. Villain
It's really complicated or really simple, it's all based on you. You can make a classic super hero of your dreams, or you can go all out and make it all from base. You can set personality, themes, styles, etc. Also, you can pick between Flight, Speed, or Movement (jumping high and shit) from the very start. The music is really this epic kind of sci-fi theme with a sexy robot lady telling you what to do. It's nice, and much better than any other MMO I played. You can pick your side, and you have to. It determines your faction.
Controls - VERY IMPORTANT TO STATE BEFORE I TALK ABOUT CLASSES (DO NOT PLAY WITH TRACKPAD)
It plays like a third person shooter. I shit you not. All your attacks are done from clicking like you would in a shooter. You can pick between physicals or from guns/range. Yes, there is a hot-bar for "spells", but they're pretty much all buffs/de-buffs. All your attacks are from comboing attacks like you would in a shooter. Keep this in mind as you make your class. Also note that playing this game with a trackpad is a fucking bitch...you can't play shooters with a trackpad. :\
You can fly (if you picked it as your trait) from one key "F", and it's pretty fluid and hella fast. Faster than walking, so I dunno why people would even use their feet if they picked flying as their trait. I guess for all the instanced stuff, you need to walk due to the low ceiling hight. :\
Powers - None (Batman + Gadgets + Technology), Elements, or Psi (I Dunno Anyone Like That)
You can decide if you want to have an elemental base, or be like batman and just use tech. This doesn't determine your weapon, it just determines your tech-tree. So you can be a gunner while having no powers (stick to gadgets), or be a gunner while sticking with a fire base powers. It's all up to you, and there's a lot of shit.
Sound - Kinda Janky In Game But Menu Music Is Great + Voice Acting
It sounds great when it's not janky. It's pretty good, and what you'd expect. The voice acting though, holy shit...I know it's not The Old Republic, but if this is a taste of what Bioware will bring, then damn...all MMOs from now on need Voice Acting.
Overall - If This Has No Monthly Fees for PC + PS3, Then I Buy
I'm really enjoying it. Surprised me when I started to play. I'm gonna pop in my mouse and play some more while I put WoW on hold. If you got questions, ask away. I'll see if I can post some images in a "sly" manner that wouldn't get me in trouble.
