Some of the Wiiware games are not too bad, Megaman 9 is a must have if you like old school make you want to toss your contoller types of games Then there is Monkey Island and Strong Bad as well and Contra, Gradius and Castlevania Rebirth games.
I would definitely throttle your connection, more like 30 KB/s DL, and maybe 5 KB/s UL. Sure it takes a lot longer, but at least you can still use internet. I had mine go up to 900 KB DL and I would have sluggish internet so I throttled it for usability as well as flying under the radar so to speak. Every little precaution helps.
