Probably ... depends on the game. What are you trying to play?
I have my Creeper Pie Minecraft survival multiplayer server running on a Pi3B+ and my friends and I play together (locally and over the 'net). The client computers are gaming PCs, but I recently got Minecraft Java Edition 1.12.2 running on a Pi 3B+
and was able to play on my server. Not as satisfying as playing on my gaming laptop at higher quality graphics settings, but it was an interesting exercise and it was playable.
My mind is like a browser. 27 tabs are open, 9 aren't responding,
lots of pop-ups...and where is that annoying music coming from?
