I know you're busy destroying the world, but how about a game of Gwent?
Yes, you all thought we already had a Gwent game. You know, the game that had Witcher 3 as a mini-game between matches? Yeah, that one.
CD Projekt seems to have noticed the potential goldmine and are likely going to announcing a standalone Gwent game in the near future(possibly at E3 next week).
my guess is it'll be webbased. i hope so, at least.
That honestly took a lot longer than I expected it to. I know card games are all the rage now, but Gwent was a game on its own, even without the genre trending. Not my thing, I suck at it, but it's a good idea. Make it web-based, make it buy-to-play, make trading cards between players the focus instead of doing it via microtransactions.
