Any recommendations on co op pc games for me and the wife were playing through valheim at moment but need something to break it up a bit we both like building games she can't play satisfactory as it gives her motion sickness

Have you tried altering the FoV on Satisfactory?
Games I'd suggest
Factorio - similar to Satisfactory in concept, but different enough that, IMO, you can play both and not get bored.
Anno -
1404,
2070, 1800 all have co-op. Don't think 2205 does, I've not really played 1800 but have heard good things. My choice would be between 2070 and 1800.
Stardew Valley - I'm currently playing this with the extended mod and am enjoying it.
Space Engineers - Some people do enjoy this a lot, I'm torn between liking it and hating it. So YMMV, have a look at some videos first!
Don't Starve Together - not strictly a building game, but there is building in it!
Project Zomboid - there's a patch coming that's, IIRC, adds a fair bit of stuff and changes others. Unfortunately said patch is currently not multiplayer enabled. Mentioned because it might be worth keeping an eye on.
My Time at Sandrock - not out yet, again mentioned as one too keep an eye on.
Pulsar: Lost Colony - was linked this the other day and it looked interesting to me
OpenTTD
Apart from that
For the King
Borderlands (all of them, less so The Pre Sequel though as that was 'ok' imo)
Deep Rock Galactic
Dungeon Defenders (AFAIK #1 is still the best, 2 was meh, 3 i think wasn't well received at launch but that may have changed)
Payday 2 - can go loud and shoot stuff, or stealth and sneak. Some missions are specifically one or the other.
Grim Dawn
Vermintide 2
Gears or War - I know a couple who enjoy the gears series, partly due to the ability to set different difficulty setting for each player. I assume the more recent ones still do this!
