Alright finally got a look at it and yep it is able to be activated multiples times. Wow that's broken as hell. So effectively someone with Force rating 2 could hypothetically throw the Death Star, think I'm going to house rule with the older version for that.
It's not really broken, if you want to allow a Force Unleashed type of game. The rules are flexible enough to allow you to scale up to whatever EU-fantasy you want. It's incumbent upon the GM to provide whatever limits they think necessary for the flavour of their game. It's also simple enough to put a cap if you need to.
That said, for my game that flexibility and the need for limits means Move-as-written is a fairly wasteful power tree. In my game, nobody is "throwing" an AT-AT, or even an AT-ST. You could consider moving an AT-AT...if you're Yoda/Palpatine/Mace. A pip-per-Silhouette is a base line for me, which means 3 of the Strength upgrades are wasted space that could be filled with tactical or control options.
