If I attack with Move (using the appropriate Upgrades), it doesn't appear to have a Critical rating. Does this mean that only Triumphs (and exceeding WTT) will allow Critical Hits?

That's what it looks like.

I suppose house ruling a Crit rating of 5 wouldn't be inappropriate though...

I recall this was asked before, but not through any official channels. As Ghostofman said, crit of 5 would be a good starting point.

Because all other Attacks delineate a number of Advantages and there have been plenty of opportunities for it to be referenced in the RAW for FPs but it hasn't I'd just stick with a Triumph as the requirement.

By strict RAW, the only way you could inflict a critical injury using the Move power is by pushing the target over their wound threshold, since it doesn't list a crit rating.

That said, like kaosoe I remember this coming up, and allowing Move to inflict a crit with a Triumph is a fair house rule. Given the sheer damage potential that Move has compared to a lot of other damage-dealing methods (especially if you're hurling objects of Silhouette 2 or bigger), I personally don't feel that Move need that many opportunities to trigger a crit, so HappyDaze's listed suggestions of Triumph or exceeding wound threshold are sufficient.

Could you perhaps use the rules governing other Force powers? Like the Dark Side usage of Bind perhaps? Or unleash?

I don't recall the rules for those specifically, so it might be OP to do so, but that might be a good starting point if someone wants something more "published".

Though personally I think the Triumph for Crit rule is just fine, as Donovan said, the amount of damage Move can dish out makes Crits somewhat unnecessary in a lot of cases.

Unleash is the only Force power (thus far) with a crit rating, as it's an unadulterated attack on the target, and I believe it's a crit rating of 4 (away from my books, so could be wrong), with the Mastery Upgrade allowing you to drop Unleash's crit rating down to 1.

Granted, Unleash doesn't have quite the amount of sheer damage potential that Move does, so if a GM wanted to assign a crit rating to allow a PC to spend advantages to trigger a crit, then Ghostofman's suggestion of Crit Rating 5 is reasonable.

Then what is it about the Dark Side use of Bind that I'm thinking about? I remember reading it and thinking "whoa, ok yep, this is why Vader can choke someone." Does it ignore Soak? Is that what I'm remembering?

Both Bind and (Heal/)Harm can inflict criticals, but those call for specific checks/ are more of direct extra effects of upgrades. Bind for instance calls for a Discipline vs. Discipline check and as long as one Dark Side point was used to activate other effects a critical gets applied and any other force points spent increases the crit by 10. Harm is similar, you're doing Harm with Medicine vs. Resilience, and then if the attack deals wounds, it auto deals a critical and then each 2 Advantage on the check is used to increase the critical by 10.

As opposed to Unleash which is closer to a normal attack and has specific crit ratings for first causing a critical and then increasing it.

Pretty much what Lathrop said.

For Bind, inflicting a critical injury is a Mastery Upgrade, and happens automatically provided you succeed on the opposed Discipline check and are making use of at least one dark side pip to generate your Force points, and adding a +10 to the injury check per every additional Force point you spend to that effect.

With Harm, it's a Control Upgrade at the very bottom of the power tree that also requires an opposed check, and you can add a +10 to the critical injury for every 2 advantage you generate on the check.

Unleash gives the user the opportunity to inflict a critical injury right out the gate with just the basic power, and thus far remains unique in that ability amidst the various Force powers that can be used offensively.
