I've recently started playing mass-effect again -- lost interest in it when losing my save file due to a hard disk crash --, seeing how reasonably well priced ME2 is and how it looks and as I want to import an existing save file.
I've completed one play through and am advancing on my second one to achieve level 60. But I'm not planning to complete the majority of the game again unless this would prove to be useful.
Therefore my question: Do achievement related bonuses (such as the EXP earned rising by 10% by completing the majority of the game) apply in mass-effect 2?
