I got my first Platinum thanks to the PS Vita and LEGO LoTR early this year.
I am not a trophy hunter, just a gamer who will Platinum what entices me to keep playing. LEGO games are abandonable before Platinuming them, but for me, they hold a charm in collecting and "getting everything done"
All my Platinums so far are: LEGO Lord of the Rings PS Vita; LEGO LoTR PS3; LEGO Legends of Chima: Laval's Journey.
Kind of easy though... try something hard.
My first was Fallout 3. Sure, it may not sound hard, but believe me, it was.
No its not. Fallout is just a grind and requires 100s of hours of gameplay. I have 92 percent in trophies from that game but I didnt feel like spending any more time grinding
Congrats to OP though.
