I was looking at my Trophies a few weeks back, saw I was like 80something% at AC2, so I decided I was going to go for it. The IGN feather guide was pretty good, but the images aren't SUPER high quality, so I just saved the maps to my computer and zoomed in on them. At the end of it, I was missing ONE! so i had to go back and figure it out, but it turns out that you can check how many you are missing in each area through the menu.
Lol, I did the same xD I gave up looking for it without a guide and used the IGN feather guide, the hardest part was collecting all of them except for 1 > <" Then you realised you have to repeat all 100 of them to find the single one lol
OH man you think those are tough; Infamous has collectibles but they don't even do an area breakdown. So unless you check them off as you go, you'd better prepare yourself to wander around for quite some time
Oh man I know that feeling a little too well. I had a map on my computer and I was checking them out until I checked off everything on the map but was missing one shard. Words couldn't express how mad I was until I stumbled across it and got platinum aha.
man trust me hardcore is easier than it sounds. You need to spend your skill points on guns, either speech or barter and sneak than rush through the game to get the trophy easily. Lockpick couldn't hurt either. I advise playing through the game a few times first just to make sure that you know what you're doing otherwise it's gonna be hard. :P I could write a book full of tips but this isn't a fallout new vegas forum haha :L I have problems with "the courier who broke the bank" :(
stevenFox is right, just to the main story line only and blow through it. As long as you have a basic knowledge of the game its super easy, and in some ways a lot more fun. But I used melle for hardcore because ammo has weight and that was space I needed for food. But i digress, you should try and get it.
