hmm to my knowledge you can do the same thing in analytics with the ordinary analytics "events" - furthermore you can track time spent between any point.. and also pull values from your game variables .. (does that make sense?)
for example.. in my game i track how long & and how many times the player plays - how long each level takes to complete, and on what level he dies ..
it's much more information than i need , but if i make a bigger game that requires much more balancing I think it would be quite nice to track things like that.
only downside so far is that i find the analytics dashboard really complicated - so it takes me a long time to find the relevant information
