Microsoft just anounced a series of rewards acoording to ur achivements points (discounts free things , etc) why doesnt PS· implements something like this ? i mean thropies are almost useless -_-
Trophies are whatever you want them to be. If you don't care for them they can just be like a familiar phone ringing as you know what has to be done throughout the story. If you do care for them, then you can start collecting as many as you can. Good, bad, it don't matter: what matters is that you're getting a free Platinum.
In all seriousness, trophies are used to distinguish numbered ranks from others on the trophy leaderboards. While not all PSN users know of or have access to such tools, or even care much about comparing trophies, there are some out there that do. And I'm sure more trophy hunters will come sniffing them out rather than they'd be the ones to set a trap in their trophy forest.
Xbox Live Gold and PlayStation Plus are very different services that can't really be compared exactly. Other than online multiplayer, I view XBL Gold as a non-gaming entertainment resource like ESPN. PS+ is pretty much all about the games and not much else...
They can't be compared, but you can definetely weigh them against eachother.
