I legit used Google sheets for my pandemic game and it worked extremely well.

We recently played a oneshot on Owlbear Rodeo instead of our usual Foundry or Roll20 and I much preferred the simpler Owlbear experience. With the others it was usually a question of “how do I do this with this VTT” and with Owlbear everyone managed their character on their own and we could just play. And I think it gave the DM more confidence to do theatre of the mind when something wasn’t prepared.

Tabletop Simulator + VR was way crazier than i thought for the first (and only) time we tried it
