Thoughts on the Unity Engine?

Site

First question some of you may be asking "What the hell is this doing on MMOsite?" I know it, I've seen you guys ask questions like that before. Well beyond being an engine that has been gaining popularity, it has been used for browser based games to add a more fluid multiplayer experience that renascences that of downloadable games. It also seems to be getting popular for normal single player games from everything from consoles, mobile devices, and PC. Why? Well, it is a cheaper platform that even offers a free (more limited) version for developers to play with, even the licensing fees are rather fair when comparable to other platforms. I know that sounded like I was advertising the engine, almost trying to pitch it to would be game devs, but I am just stating the facts of what I have seen.

As for the games made with it, the only ones I have really played are those using the engine for browser based games like Battlestar Galatica, Family Guy Online, City of Steam, ect. From what I have gathered/seen, for being a "budget" engine, it seems fairly solid. Each of those games bring their own aspects, and while the Battlestar/Family Guy online renditions of their perspective shows are rather gimmicky, they're better than they would have been if done using a more simplistic engine. The problem right now is that there aren't any really serious games that seem to bring a lot out of it, at least in the mmo-front. There are hopefuls like Shadowrun Online, which I am looking forward, but it is still yet to be seen how much they will bring out with the engine.

Also being an as I put it, "budget engine", it also means that there is more room for would be devs to try to create things. Worrying less on the cost of the engine and more on the actual servers and developing the games, which is good from a gamers perspective, considering there will (hopefully) be more well done options for the free market. I know - they could just skip getting a pre-built engine and work on things from scratch using coding platforms like Java or C++, but that takes a bit more time and more time spent on creating a platform is more money lost and the longer the game is actually out there and playable to the masses. I mean the engine comes with a built in physics engine, ease for pipe-lining art, and built in networking classes (which if you fail at networking programing, makes your job easier)

All in all I think it is a rather cool engine which potential hasn't been reached yet, and it would be interesting to see what gifted people could do with it. What do you guys think of it, and have you played any games using the Engine?

tl;dr - I like the engine, what are your thoughts on games using it?
