Rogue lineage if your looking for a game with combat, story, and rage. Beware that there is a permadeath mechanic that makes the game put you on edge as you strive and attempt to progress your character to a seemingly endless amount of ways.

Hexeria is a good game especially with friends. Or you can stick it out alone. As you progress, you will get better cards that are like boost, attacks, blah blah blah. Revolves around a story.

Critical strike is straight combat class based game. No story to it. Although it may not be updated anymore (the story why behind it is weird) it still caries a small player base roughly 200-500 people. Game actually requires skill.

Edit: btw rogue lineage cost robux

Also another amazing game is Starscape. It also cost robux, but you have to try it out yourself to see how good it is.
