The first thing I check for is if a game is Terraria. If it isn't, I play Terraria instead.
All kidding aside, I tend to enjoy games that involve exploration, character development, and pleasent visuals. Good sound design is also a must, and I prefer games to be at least somewhat action oriented.
None of these things are hard and fast rules for me, of course. I like a lot of different games.
What are you talking about?

That took me like two second to find. You can also use addons, like this one for Qwant:

Which I like. But none of this is hard or "obfuscated", and it's literally identical to changing or adding a new search engine on Waterfox.
I have a lot of issues with Mozilla, not least of which is their reliance on Google for income. It's like hiring a dingo as a babysitter. But c'mon, man.
