Monopolies are amazing and good for the consumer, right?!
But oh no, you have to download another launcher - The horror.
What you call monopolies gave us:
-Free steam key generation for devs which means a LOT of 3rd party stores such as Humble Bundle, GreenManGaming, Voidu, Razer Game Store all competiting in term of price, yet not skimping on the service since we still get steam keys to redeem on one big solid ecosystem.
-Lot of fonctionnalities that made PC gaming move forward such as Steam Input, SteamVR, Family Sharing, no online paywall, Big Picture Mode, Inhome streaming, Mod workshop with one click.
-Open source stuff such as a free gaming OS with SteamOS, contributions to open source libraries for Linux, Steam Proton allowing Windows titles to run outside of windows.
-A big ecosystem without ostracism against indies, which led to the PC market gaining a second life and publishers releasing their games on PC again. If today, I can play japanese RPGs on PC, that's because there was a big "monopoly" where everyone was to buy games. Yep, that's why I can play DQXI on PC today.
What you call competition brought us so far:
- New closed standards with UWP which prevents from touching files
- Game exclusivity bullshit on a platform that is supposed to be open (Which means no price competition)
- Broken launchers (Bethesda, if you can read me)
- Fragmentation between some multiplayer titles despite being a PC game (Dying Light on GoG, Call of Duty on Windows Store)
- Dead games and dead services (Games for Windows Live. Remember that one ?)
- Harsh conditions for refunds (Origin limited to selected titles, GoG limited to the game not working for you, Epic limited to 2-no-question-refunds per account).
So... YES ????
What you call monopoly has been a blessing for PC gaming as a whole and even gaming as a whole.
What you call competition has been a disaster.
