I'd have to say my favorite would be Jetpack Joyride! Played it a lot on the PlayStation Vita and loved it. I think it's definitely a perfect pick-up-and-play game.
Well as the community manager for Archelyte Entertainment Studios, I'm particularly excited for Ninja Surfer to come out on iOS and Android!
Recently, we are developed one endless running game, "Swing Master Poka". Here is the link: http://www.redappletech.com/our-portfolio/swing-master-poka/
I love Jetpack Joyride too but I also love a newly released game (not mine , it is released from a fellow I found on TGISource forums) called Shadow Obstacles . One more odd but good endless runner is race the sun ... it is odd cause it is for pc (on steam) and it has stunning visuals as well as VR support.
