Just finished Sonic Generations - it's the first 3D Sonic game I've played, so it's certainly a very different experience.
It's good how despite essentially being forced to play through each level as both classic Sonic and modern Sonic, that it doesn't feel repetitive for the most part. Some of the later levels designed after 3D Sonic games don't transition back to the classic style as well as the old levels are adapted for the modern style.
I'd say that I prefer the modern Sonic, and the game certainly does a good job of showing that side of things off. Really good graphics apart from a few occasional glitches with the camera wandering off.
Another thing I've been playing a bit of, I finally took the plunge a few weeks back and bought Sim City in a sale - I had been avoiding it because of the always online thing and general bad reviews, but it was about $25 on sale, so along with the news that Offline mode is coming soon, I decided to go for it.
The very small size of the cities is my main complaint, but the odd financial system really puts a drag on playing it for that long - you just seem to be constantly waiting for cashflow to do anything, with basic services requiring huge amounts of money up front.
That seems to flow from trying to shoehorn online into the game - you can get bigger loans if you have a finance department in the region - so in my not wanting to worry about what other people were doing - I basically got to the point of building several cities in a region and getting them just big enough to build the relevant departments and resources in the hope that eventually I can get off to a good start.
I've got enough game time out of it for me to not feel like I wasted my money, but it's not a great game and I certainly wouldn't recommend it. At least it's better than the totally overwhelming Cities XL 2011 that I picked up in a Steam sale before it - that's way too deep of a city simulator for me.
