Except for some sleep, I went straight through the SP mode in one day on my PS3. It took me 11.5 hours gametime, so you can tell I'm not much of a gamer!
The next week, my brother and I started the coop mode, then I left the game with him to practice in SP mode (he had never played the original, so everyhing was new to him.) The week after that, I went back and we finished coop mode in two nights (side by side).
This week, he got his own copy, and we are working our way through coop mode online so I can get my trophies. Unfortunately, in the middle of play, there was a power blink and my UPS didn't handle it well. It scrambled my profile. 3ven though we had completed courses 1 and 2 the night before, I lost those trophies. We basically had to start over. Once we are done, I will only need to hug two more online players to get 100%.
Yesterday, I got my DS3 controller working on my PC (thanks,Motion in Joy), and have started playing SP user maps. I am looking forward to meeting friends online to play some of the coop user maps, too.
Does anyone know if the coop maps need to be loaded on both machines for an online session? I don't know if my brother plans to get the game going on his PC, and he's the one I usually play with.
I love the maps I have seen here, so far! I would need to be tutored in Hammer before I could even begin to produce stuff like I see here. I can't even create decent levels in Little Big Planet, which is much easier for noobs.
