I've personally had no issues with Steam, even had a CD key transfered with their help from my brother's account to mine when he accidently installed a game I purchased physically (but required steam to play) on his account.
but that was years ago.
I don't have issues with Steam but these days my primary store is GOG (
www.gog.com) new games and classic games in digital copy but no DRM so you can store installers on external drives for safekeeping for example. Or you can use their goggalaxy program which is similar to steam in the way that it keeps your games up to date and have game's achievements if you care for them.
I rather have games without DRM's but if I have to because it's not available on gog I use Steam as my experience Steam compared to others like Origen, Uplay, Epic games etc etc has been good in my opinion but always fully understand the terms and conditions before you commit to buying something.
and in your case befor starting playing it I'd suggest if it's in a bundle to try each title by launching them and see if it works so if it doesn't you won't run into issues with refund policies how absurd they may be.
