I can echo that sentiment. The MQL starts really slow and has a lot of exposition overlord as is normal for Bethesda games. Once I started doing side missions for the UC Vanguard and "pimped my ride" xzibit style I got hooked.
Exactly what I experience in every Bethesda game. Boring ass main quest line where a bunch of British people telling me about starsigns or some shit and then I joined the vanguard and never touched the main plot again because exploding pirates and space hobos while exploring planets is where it's at.
