If u think about it its fair because Gold trophies are worth alot more than Bronze. Bronze trophies are really easy to get where Gold trophies are harder so it makes sense. Reason why Killzone 2 has so many bronze is because it has many dlc trophies and all are bronze and quite easy to get. It all depends on the Developers what trophies they decied to make. Imo if a game has 3 golds then its good.
If u look at Terminator salvation it has 11 golds, if u play on hard and beat the game u will get 11 golds and 1 platinum and it takes like 4-6 hours. In Killzone 2 u get 1 gold for beating the game on Elite, which not easy but after beating the game Killzone 2 on Elite i can that i would be more proud of it than get 11 golds for beating Terminator salvation.
