That's easy.
I won't.
Aside from the occasional Nintendo release, I've all but erased AAA games from my review schedule. I didn't become a video game critic so I could jump through more hoops than the Westminster Kennel Club. There's no culture in GaaS. It's all just a meaningless grind.
It's the future though, I don't think you can escape the GaaS problems you talk about, it's already here and not just on the multiplayer games with all games getting post-launch updates and season passes etc. The day 1 reviews are sometimes inaccurate within just days after the launch.
But don't overthink it, just write your review as usual, talk about the core gameplay and story and what not, score it, and if there is a meaningful update you can update the score. Done. It's no different than keep talking about a game and it's changes on this board, you can even post your own comments you make here in the updated reviews if you don't have the time to write them down again.
Any update is better than just leaving it at the day 1 version which few actually get to play.
I just think we need to adapt to the current way the game industry works. As of right now we're essentially rating and talking (and fighting) about how polished and optimized the games were at launch day.
That doesn't help the consumer much. :/
It's great that you're focusing on smaller games though, you're doing a very important thing there. Even just shifting to review the PC, Switch or Xbox version instead of the usual PS version is great.
