I have not played Genesys, but from what I understand it is basically the same as the SWRPG system, with some minor name changes (spells/magic instead of force...etc).
Don't know how Shadow of the Beanstalk is handled in play, but have used books for that world for fun.
The system, as a modified SWRPG system, should be relatively flexible. It is more of a story telling system in some ways than a straight up black and white success system (D&D is more black and white in success).
In this, it means you can succeed or fail, but you can also have side things which are positive or negative even if you succeed or fail. For example, you could fail, but at the same time that failure turns into a positive. At the same time you could succeed, but that success turns into a pyric victory.
As an example, let's say that you are using your a cybernetic site to snipe a headshot at an enemy for an assassination. You roll a success, but at the same time the dice also show that there is a negative effect from the is success. It is then up the Game master to say how this is implemented. So, it turns out that you assassinate the target, but your assassination is noticed and attention drawn to you. Your face ends up on the holovids and news and you are now a wanted individual. There are several organizations after you, and you are being cornered in you hideout even as you set up to flee.
Or, on a negative side, let's say you fail but also show a positive event. You thus miss, but in missing you accidentally hit a gas main near the target. It explodes, taking out the target and masking all evidence that you were involved.
There are some differences between the systems, but are very similar overall. If you know one, you know the other.
