I just want to say God of War 1 didnt have issues for me. God of war 2 does have issues, one trophy didnt ding last i played it, a storyline. I found out last night the game has issues though. When i got to the part to free horses of time for the temple. One of the levers was bugged, and the enemys in the area was as well. I also had a lockup before that part.
So bugs in the game can cause issues with gameplay and storyline is what im figuring. Ill bet the first God of war for the psp dont have issues but the 2nd one does, and ill bet the first God of war for ps3 dont have issues which is part 3 but the 2nd one does.
God of War: Chains of Olympus on the PSP primarily had an issue with the analog nub. Rotating that tiny mini-analog was painful in some situations. On the PlayStation 3, the same game can be played, and like the PSP version before it the analog control is based on the PSP port rather than remade for the PlayStation 3's DualShock controller.
It sounds as if all you can do is try again until the trophy pops... unless there's something you might have missed?
I read up on it and alot of others had issues with that same trophy popping. I hope this time it does pop though cause im getting all the ones i missed this round.
