Game review time!
I'm going to keep this short and sweet, because I want to get a new post, but don't want to spend much time on it.
To start off, i've been playing since the beta and boy has the game changed a lot.
S2 keeps their selves busy and constantly updates this game, which is a good and bad thing. If you take a month or so break from gaming, you'll come back and not know what to do. I recently came back to the game after a hiatus and there are HUGE game changes and hero changes.
They keep the game up to date with new content, but I think it needs to be fed out little by little so we don't have to relearn it all again.
The gameplay basically focuses on an initiator, supports and a carry, it's not always like that, but generally the main focus is to get one guy on your team geared up quick. This game has a huge learning curve from a pub to competitive.
Balance issues are out there, but S2 usually fixes them up fairly fast.
If you're looking for a good cheap game that will hold you over until DotA2, I would get this.
Kind of a lazy half assed post, but whatever.
