With so few good new titles being released these days, especially by major studios, I figured I'd make a thread for everyone to share your favourite classic or older games, especially if they're lesser-known titles that others might have missed at the time.
I'll open with The Saboteur (2009), Mercenaries (2005) and Saints Row 2 ( The 2008 original)
The DS and 3DS had a surprisingly good library in Japan at least.
JRPG gems like radiant historia, Golden sun and some of the better fire emblems where on there. It can all be Ahem "acquired" since Nintendo stopped supporting the platform and has the benefit of being on a totally offline device and memory card if you do.
