Possible steam discounts

Wait for the spring sale and see. Until then, nobody really knows.

Simfest: Hobby Edition, Die-a-lot Sale, Racing Sale and Next Fest: June 2022 are the next steam events/sales and i think you won't see these games on sale, so better wait for steam summer sale or go to a key shop/steamtrades

For Dead or Alive 6 check out alternative stores. You can get them a lot cheaper if you're looking to get the games. I don't know which Dinasty Warrior you mean, so I've assumed the 9th. That may take a while. If you want to get an older one, check DYNASTY WARRIORS 8 as you can get it a lot cheaper.

Be mindful of the keystore. Nobody knows where the keys are provided really, but it's a cheaper alternative really.

PS: Keep in mind that Dead or Alive 6 is free with the core-fighters, so if you want to mess around with the game, you can. 😃
