I'm looking for a fun inexpensive game to buy

Heroes 3 of might and magic. Its classic from old days. Im playing it for like 8 years and im still having fun

Definitely try Terraria. Really fun game for the small team that made it and how far its gone

war thunder or world of tanks, they don't require to pay much to play with comfort

Hmmmm, i think these suggestions will be good for you.
Limbo
Inside
Cyberpunk
Blood and bacoon
Watch dogs 1/2

play Cities Skylines for single player, and terraria or dota2 for multiplayer with your drienfs

Apex Legends and Warframe are free and what you need.

i will say space engineers, its fun and simple game to understand and cheap too

Warframe is the way to go, the progress they've made since it released is astonishing.

If you can tolerate looter shooters, I'd recommend Destiny 2. Great story, a lot of repeatable value, PVP, PVE, and PvPvE avtivities, and with the new expansions theirs a some grind that leads to very, very, rewarding loot. Oh, and not mention that the raids are. Amazing.

i would say play pubg free on ur phone bcz its too good
