This question regarding the 'best cross-platform 2d graphics engine' (Cross Platform 2D Graphics Engines) shows up as the first Google result when one searches for 'cross-platform 2d graphics framework'; however, the contents are now five years old and while some answers are still applicable a lot of it is out of date and hence misleading. (For instance, Unity now directly supports 2d graphics.)
I think there are two possible courses of action to correct this:
Either: 1. Open the question and allow it to be updated. 2. Delete the question.
It's certainly an important question to answer, but if the StackExchange format is intended not to be used for this kind of question then I think we should delete the question.
There may be other options (somehow mark it more obviously as outdated, etc.) but I think something needs to be done.
