Fast pace, easy to pick up, and balanced, with plenty of unique and fun characters you can tweak to your liking
This game is highly addictive. I've dabbled in League of Legends and Dota, but they were too overwhelming, and I didn't want to invest the time into them. The communities for those games were also rather harsh. Awesomenauts just oozes with fun, lighthearted enjoyment. From the title theme song to the gameplay and the quirky comments that the characters make, this game is comical and entertaining all the way through. I play with my housemate at least every other day because its so easy to pick up and play a 15 minute game between classes or before bed.
I guess you might want to hear more about the game: it's a classic MOBA from the analytic view. There are tanks, ranged gunslingers, AOE moves, etc. You can unlock new upgrades for all of the characters and fine tune their abilities to your liking. When I play as the insect-like Gnaw, I can either focus on beefing up by acid to deal huge damage in close proximity, while I beef up my bite to deal a wombo combo of damage, or I can make my acid slow the enemy for several seconds and have my weedling minions deal tons of damage. If you didn't quite understand that, that's ok, it just means you have to pick up the game and go try it out! One of the cheapest games I've bought on steam, and I've put the most time into it.
