[Tacops] TacOps v4 Online Sales ?

[Major H]

Anyone very familiar with Steam, Epic Games, or other online distributors ?

I am financially good right now, without selling anything.  But I wonder
once in a while if I am leaving money on the table that could buy more
trinkets for the grandkids and polish the old lake cabin a bit.

TacOps v4 is somewhat dated/retro, but it is stable, and I get a few emails
weekly asking where it can be bought.

Thoughts, suggestions, pros and cons  ?

Best regards, Major H
