In short:
The game is so much fun, I like very, very good!
Story: 3/5
Humor: 5/5
Gameplay: 5/5
Action: 4/5
BUT: it is nowhere mentioned that the co-op mode with deieser version initially does not work!
For activation via Steam is necessary to say:
1. You need Steam and must activate its Borderlands there
2. You have the full game download again, although it's available on DVD. The same also applies to the addon! Ie about 10 GB download! Just to avoid that I have the much more expensive DVD bought variant!
Conclusion:
Arrived and play Koop is not! Especially with a slow Internet connections annoys you so!
Therefore: I rate this the DVD version, which Steamkey I would give 5/5. The game ansich is super! But this product has at the beginning just took me too nervous. You should download the necessary to write!
