There is nothing better than having the game already downloaded, installed, and ready, only to not be able to run it because uplay is down. I even watched a movie Non-Stop to kill time (loved it, Neeson is certified bad ass and I hope he keeps making action films forever) and uplay still doesn't work.
I've not been able to log into UPlay since Tuesday morning (UK). You'd think with a game that pushed so much about online features they'd take the hit and just invest in the servers. Especially since every game from here to forever seem to be "always connected seamlessly"
Let's hope Ubisoft realizes this in the future and instead uses Uplay as a service for unlockable content and community, instead of a game client. People flocked to South Park The Stick of Truth because of no Uplay.
They could always negotiate with Valve regarding how much money they get from game sales.
