The real perk or feature of the DT 770s is that they are closed back so block out a lot of sound and also keep it in so you don't annoy people around you as much. The fact they're cheaper also makes them attractive but I'm pretty sure you'd prefer the sound out of the 880s or 990s.
The 990s are supposed to be more 'fun' with more bass but I doubt the difference is huge. I've listened to my MMX 300s, my old DT 990s and my T1's and I would happily use any of them for music or games
Decent headphones really are the best thing since sliced bread if you've never had a pair before

but if you don't think you'll mind then DT 770s might be fine
