I'm going to write a simple tile-based RPG game in Javascript, with a big, tile-based map. I looked at this list of JS game engines, and found out that the only reasonable choices for me are MelonJS and ImpactJS (because of the map editor). Now I see that:
- MelonJS is free and open source, ImpactJS is commercial ($99)
- Both seem up-to-date
- Both seem popular
- Both have tile-based map editors (do they differ much from each other?)
- Both draw on canvas
- Both have sound support
Are there any other important differences I might have overlooked?
Do you have any experience with how they handle big maps, made of big tiles?
How do they compare in terms of performance? I'd like to be able to run my game in full screen.
