OpenRA has been promising Tiberian Sun/Red Alert 2 support since 2011

Instead of working on finishing it though they just add more tedious features to RA1 (an in-game encyclopaedia, really?)

Does every engine need to support every game in a series?

I think it's fine for OpenRA to focus on what they enjoy most, and others to cover other games.

It was kind of a blast but a couple of newly introduced bugs this year or late last year totally killed it for me.
