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)
I have recently been playing Unicorn Overlord, it is very similar and is really nostalgic to me with Ogre Battle 64, lots of similarities in a great way.
I don't really suggest UO as I see some of the localization issues and some of the dialogue choices, but outside of some of that stuff it's a great game.
I do definitely suggest Ogre Battle 64, I think it is a great, interesting take on a strategy game for console. The revolution/rebellion type storyline I really enjoy, and the RPG mechanics that tweak how the game plays out in small ways are fun too.
I also agree with acp_k2win with PS2 being peak, for me it was that entire generation as I worked enough during summers to get each console over the years and there are countless good games from PS2/GC/Xbox/Dreamcast (shamefully including my forgotten friend).
