Replying to this one since that was my first impression. On closer look they did seem quite different.
Gameplay, goals, all of that is similar to screeps. But the game board and therefore the mental model itself is quite different. Where screeps feels like an endless multiverse along the lines of old school browser games like oGame, yare carries a feel of a more quick starcraft battle. Definitely not a copy even though it carries similar mechanics.
Basically, I feel like I could do games on yare randomly whereas screeps has always felt like a long term investment I need to make.
EDIT: Also also, yare seems to be far more simple for the moment in terms of environments and resources but that could change in the future and I'm looking forward to developments there.
