I thought it was okay. It fizzled out pretty quickly for me as it felt half-baked and overly "gamey", which kept breaking the immersion illusion for me. I never did finish it. But I started over when Phantom Liberty dropped last week and it feels soooo much better. The immersion doesn't feel like it's being killed by a thousand cuts... everything feels more natural and believable now. It still has it's gamey moments, but they are a lot less obvious now.
