EXcluding fighting games, there would be no online game at all, and even then, there woukd be a lot less emphasis on e-sports, tournaments, etc. Those things would be back just as they started: as hobbies, and most players would have to find a REAL job, living a real life.
All the games would be lenghty, cinematic, intense, immersive sims, single player only. Games like the Deus Ex saga, God of War, Spider-Man, Red Dead Redemption, etc.
There would be a lot less open-world games, and many more level based games.
Customization would be 100% free.
Loot boxes, gambling, cashgrab mechanics, etc would be banned and persecuted the same way as piracy.
Mobile gaming would be just a couple good java games and a lot of retrogaming emulation on the go.
The only successgul genres would be fighting, first and third person shooters, action games, action adventure, RPG, action RPG, JRPG, cinematic experiences (Quantic Dream games), point and clicks, survival horror, dungeon crawlers, Tactical shooters, platformers.
Sports game would be released once per fneration and will be mega-patched every year for a minimum wage, unless there is a total graphic and gameplay overhaul, no longer copypasted Fifa, PES, NBA, WWE games with updates rosters released as full games, just patches for a price if 9.99 €.
Correct value currency transiction according to the stock exchange fluctuations: I am sick of spending 10€ for something that costs 10$.
10$=8€ or slightly more, I don't wanna pay a good 20% more for the sane good bought under dufferent currency.
The same offers for all the markets: for the reasons above, I am sick and tired to make alternative accounts just to buy at a discounted price for the US or JAP store.
Fan Patches and Mods would ve allowed on consoles too.
All digital goods would be tax-free.
All licenses have no expiration times.
All games should be released with the english language incorporated from day one, even japanese ones. All the other languages options should be kept as optional. At least Multi-10 should be mandatory (ENG, SPA, FRE, DEU, POR, ITA, JAP, RUS, CHI, HIN).
Public founding of indy developers.
No politics in videogames, like, at all (except punching/killing Nazis, it's too much fun).
