MarchieB: Just a curious question, why is everyone so Happy about this? I don’t get it. Is there something I’m missing? What’s so good about Steam?
Steam is a well-known gaming platform in the gaming community. Lots of games of all types and genres are available to play on it. For me, it is a huge win that WGT will be available on Steam, because I already have other games (including another golf game) that I've purchased there.
It will be interesting to see what (if anything) WGT charges to purchase and play their Steam game. The other Steam-based golf game I have is somewhat different in that it's a one-time purchase, but for that one-time purchase you get unlimited balls and can customize your 14-club bag any way you like... for instance, you can swap out a 3 iron for a 3H, a 4 iron for a 4H, etc.
It looks like the release date for WGT on Steam will be March 12, 2020.
