Put Sly 2: Band of Thieves on the backburner for a bit.
Due to GTA Trilogy DE hype, I started one of the GTA's I've never played: Liberty City Stories (PS2)
And I'm doing something I've never done with a GTA game before either: going for 100% completion!
It's both satisfying and frustrating chipping away at all the game's activities available, even if some of them have the potential of being frustrating in spots. I currently extended my health, got access to pistol/shotgun/armor near my safehouse + infinite sprint + being fire proof + got the fastest taxi (car overall? I dunno, lol) in the game, haha.
For a "PSP game", while I'm feeling every activity/mission being very short compared to what you'd find in San Andreas for example, I'm having tons of fun. The AI is insane, the traffic is insane. It's a blast.
