Mass Effect is good, but there are more fun ways to go blind.
The games are a mix of third-person cover shooter and RPG, so they're not very text-heavy during missions, but you can spend quite a lot of time between missions talking to people and learning more about the Mass Effect universe. Except the first game, where the first several hours of the game are spent walking around talking to people and then your squadmates run out of things to say halfway through the game. The sequels are more balanced.
If you like BioWare RPGs, there's no reason why you should miss out on Mass Effect. And if you've never played a BioWare RPG, this is a good place to start, as it's by far their slickest and most accessible series.
