I grabbed Cities: Skylines finally and lost 3 hours on it immediately. I can see why people laud it as the true successor of SimCity 4. So worth the price. Also grabbed an RPG called Siralim that reminds me of Dragon Warrior Monsters for the Gameboy Color. Haven't gotten to play it yet, but am excited to try it out.
Cities is probably one of the best games I've ever bought. I really don't play it a lot (or anything outside Rocksmith, really), but I've enjoyed every minute I've spent in that game. While the traffic mechanics that can cause growing pains can be annoying, it's still fun watching your tiny city grow into a booming metropolis. I'd love to go play some more and knock out some of the monuments.
My holy grail in skylines is to make a city where it's always faster to walk to the next district than take a car. It works up to a certain size, then the emergency and civil services cause a break down because they can't get to places fast enough. One day though...
