>in Cyberpunk you can lock yourself out of being able to do certain endings if you don't do sidequests
That is not more or better reactivity, anon. That's also basic stuff most RPGs do, including Mass Effect.
Mass Effect 1 will result in Wrex dying unless you did his loyalty mission and on that very same mission 1 of your companions dies for the rest of that series run, impacting ME2 and ME3.
It's like you've never even played an RPG before.

>Just like ME's Shepard.
In ME you have way more control in shaping how Shepard behaves and is shaped. Some of it is even extremely obvious with the Paragon/Renegade stuff, which also impacts what choices you can make.
Again, it's like you're not paying attention.
