Can you play PC (low end/old) games actually on the iphone with or w/o jailbreak?

Like you actually have the game installed on your iPhone and you play it with like a apple keyboard or something. So say I wanted to play like Penumbra: Overture pretty old and really low end game. Could I play it on my iPhone with like a jailbroken thing you have l download or something and a apple keyboard or a Bluetooth keyboard or something to play it. Is there such a thing?

You can surely play the low end games on the iphone without jailbreak if downloaded from the below source. Enjoy!
