What are /r/supportivegames' favorite Products & Services?

From 3.5 billion Reddit comments

I'll start this off; I was able to level up (level 5 now!) and actually capture a significant amount of portals in a populated area on Ingress this week; I was able to even obtain some mind control fields.

Heroes of the Store looks interesting, but the only MOBA I have ever played is Awesomenauts. Maybe I'll give this a try.

ETA: Is the community any friendlier than LoL or DOTA? Neither of those games' players are very welcoming toward noobs, it seems.
