I promised a review. I'm not good at writing coherent reviews, so I think I just share some feelings. May be a bit messy :P
I like ambitious projects and deep storylines, but I also enjoy simpler things. OCaD belong to the second category, with fluid gameplay and intuitive objectives. I don't like situation such as having no idea what to do despite directives and stuff. First interation of BP: Tenebra is a nightmare in this case. Missions may be challenging of course, but their mechanics should be clear for players. OCaD fulfill this point well.
The only fail I had was hacking satellites mission. At first I wasn't sure if enemy fighters are going to scan me, or they ignore me or whatever. I flew too close, engaged, destroyed one wing... Than I realized I screwed up, so I replayed and this time I circled around enemy wings. Maybe some messages warning about proximity to enemy wing would help?
Gosh... Move the hangarbay of Centurion or make it bigger :P. I had no idea how to scan this thing, so eventually I just glided into the hangarbay recess facing forwards. I almost died. Don't get me wrong. That scanning was one of the most interesting scanning mission I ever played, along with one nebula recon mission in Scroll. Whole concept of doing scans on glide is appealing to me. Some intercepted chatter of rebel ships around would significantly enchance that part.
I wasn't bored playing OCaD. I was flying different crafts, each one with it's own soul. Although your mod is quite minimalistic in terms of modpack, I didn't feel like I'm shooting the same things over and over again.
Gameplay is faster than standard FS flying model, but not too fast at least. I was skeptical about autoaim at first glance, than I realized it balances lack of missiles on some ships well. Still I think that every playable craft should be equipped in at least some token, Tempest-like dumbfires.
Overally missions were well-balanced. I had to do some maneuvering to achieve my goals, but also I never felt overwhelmed by neverending waves of enemy ships. OCaD was... Relaxing in terms of gameplay.
Original universe is a challenge. Ship design mixed music and nebulae created healthy and fresh experience. I would like to know more about the lore, our faction, systems and everything else when I play anything. Command briefings are powerful tool useful for worldbuilding, so next time gimme something more to read :P.
In terms of bugs, there were very few and I don't remember anything significant. Nothing game-breaking, and some of them are likely to be fixed by this day. No popping errors, no broken missions, everything was working correctly.
The only thing that bothered me was the last mission. I just fly and shoot more and more fighters lashing pirate command ship with stream of bullets and missiles from time to time, while pirate warship just stand idle... Same as our ships. Gimme more action! Make our homeship attacking the Centurion. Add some dramatic maneuvers and exchange of fire between them. Maybe hold the pirate cruiser, and deploy it to attack our battleship when Centurion is almost dead? Dunno... People expect some epic **** from the last mission. And ehh, the Gladius died so stupidly...
Overally I found OCaD as nice, first project of aspiring modder. Something fresh, original and introducing new setting with plenty of stories to tell. OCaD is a good foundation for future projects and relaxing experience on it's own. Perfect for some long evening, when you just want to drink a beer or two, and shoot some stuff.
