First when joining PC gaming you should add augmented steam to your browser, this extension will other oficial stores to the steam web page. this means that you can see where a game you like is being sold for less.
second i highly recomend taking the time to play a few strategy titles.
lastly if you don't mind some old classic games like half-life, World of warcraft, dungeon siege, baldurs gate,etc.
here are some screenshots of games i really like:
warhammer total war
I'm a bit biased on this one since i did the OT
Big battles with 1000s of soldiers, from afar the battle is like this:
you can zoom it to be very close to the action
Crusader kings 2 ( base game is free)
crusader kings is all about managing your char and managing your family so you can lead your dinasty to glory! except when you find a witch and she "gives" you an elixir that makes you imortal.
They are billions
Maybe surviving an zombie infestation is more to your taste?
Total war three kingdoms
If you like more grounded settings but still enjoy a sprinkle of fantasy why not take a look at this marvelous total war? lead your warlord to become the emperor of china during the three kingdoms period, just beware of Lu Bu
Football manager
In the PC platform you can play the beatiful game in awy you might never have. While i like signing big starts i'm more of rising youngsters into stars type of manager.
Battlefleet gothic armada 2
In the grim darkness of the future there is only war! In battlefleet you lead an armada to try and keep the ocularis system from falling to several species. It has some great space battles.
But maybe you prefer to explore the galaxy and instead of war you prefer other approaches. Whatever style you choose, stellaris has it.
I have 100s of hours in the previous games. I think they are some of the most fun i had in video games. I'd recommend you give them a try,
