I finally made the plunge and bought GMS2. It has been out for just under a year, so I am not that late to the game – however, I do have other projects going that I have to finish first, before diving heavily into Studio 2. But it is very exiting. No more backgrounds, now you use sprites! Everything has layers now. Rooms can have children. Totally new UI, made from the ground up – this time in C#.
