It's been a while since I've been doing game dev but I've decided to get back into it. I've mostly been doing webapps, and mobile apps but have done some game dev in the past.
I am looking at creating a 2D side scrolling game for Windows 8 and was wondering what engine would be best to do it in? I'm leaning towards either MonoGame or Unity. Any other suggestions are welcome
I'm pretty comfortable in developing in any language but may need to ramp up a lot with C/C++.
