I've already played most games people always recommend, like Resistance, Tales of Eternia, Crisis Core and others. They eventually get boring, so I'm wondering if anyone can tell me a good game that no one really knows about, but still pretty good. I like RPGs most, but any good game will do. Just don't say something everyone always says like GoW and MHF (I honestly didn't like that game).

Modern warfare 2 and Final Fantasy

Dont you need to do it by yourself to get the achievements? I cant remember.

I did it by myself, it was HELL. Especially Cortana, like I have trouble doing it in Normal, makes me wonder how the hell I did it in Legendary

Assasin Creed Definetly.

Sounds cool, but gets disapointing, like Fable 2, but Fable 2 isn't THAT bad.

Both CoDs are pretty short, but make up for it with great online play and Nazi Zombies

Fable 2 was a disappointing for me it was short and easy. The 1st one was longer and little bit more challenging.

is extremely hard*

Gunslinger was hilarious for me because I did it with my friends.

I HATED Beat Cortana in Legendary on Halo 3, but I still beat the game in Legendary (Theres a good guide on youtube) and Mile High Club it extremely Hard. My bro got to the last part, but killed the hostage by accident >.>

Lol Pokemon Sapphire.

If we're talking about any system, then Cod:4 (Story and 8th Prestige) and CoD:WaW (Story, I think 5th Prestige and lots of Nazi Zombie play time) On Xbox 360.

And when I played Marvel Alliance on my Xbox 360 (It came with the game) it was really boring and I had to use cheats to make it a little more fun and I think I still got Achievements?
