Toribash is quite possibly the best competitive fighting game I have ever played due to it's unique method of controlling your actions. It's almost entirely unheard of tho.

Freespace 1 & 2 deserve a mention here. Old games, so smaller in scope than modern games. But I feel they can compete still.

Plants vs Zombies on PC.

Great, unique, iconic, still fun to play. Its biggest achievement: I have brought a lot of people into the hobby by making them play this as their first video game and there wasn't a single one not having fun. Tower defense is as a whole an underrated genre if we talk about the best games of all time. It also is a game that offers achievements that add a lot to the gameplay by challenging you to change your tactics.

They of course had to make the second one mobile only and on top ruin it with microtransactions. :( Greed is why we can't have nice things.

Trog.. I played that game for days

It just occurred to me that Death Really (1995) would deserve to be talked about as well, it's just an incredible little game.

Pirate Trainer & Uru: Ages Beyond Myst

I remember trying Pirate Trainer in a Nvidia game booth when VR was new. It was incredible, years later I get a VR headset and its the free game. I don't understand how no one has improved upon it.

Uru was the first puzzle game I thought struck a good balance between physical and mental puzzles. They were set at a level that felt challenging but not impossible and laid out so you alternated really nicely. Myst Online actually went backwards in this
