In no particular order - Injustice: Gods Among Us Marvel Future Fight WWE Immortals Final Fantasy Record Keeper (not playing it, got tired of it but a fantastic game for FF fans, which I am not) Man, looking at all the games I've tried and that is a depressingly short list compared to the number of F2P games I've downloaded at some point or another.
Here are some of my favorite freemiums: Adventure Beaks Temple Run series Hearthstone Marvel Future Fight Vector HD Phoenix HD Spiderman Unlimited Dead Effect Cardinal Quest 2 Checkpoint Champion Quest Keeper Tap Titans Punch Quest Flapthulhu
I really liked it, but if i want to play a moba, LOL is always available to me since 90% of my time is spent in front of a computer (both work and home).
Yeah, my problem is that if I wanted to play LOL, I still couldn't because my computer is about 6 years old and almost explodes when it's watching a movie. Gotta fix that eventually. But until then, I got my iPad.
