The characters are stupid (10 year olds could make better choices), the plot is predictable in many places, there are lots of filler things included just for people who want to waste hours collecting things, game mechanics which could be really useful turn out to be really useless, most of the cast of characters is ultimately not worth using, and the ending is  really anticlimatic.

I could make a thread going into actual detail if anyone cared, but that's the gist of it.

Tales of Symphonia is extremely mediocre and in many ways quite awful as far as RPGs go.  The problem is that there were so few RPGs on the Gamecube worth playing that it got a lot of undeserved hype and, even today, still does. 

Second Sight. I really loved this game. The story and how they handled it was very well done. I also think the powers you get add to the fun gameplay and strategy in playing it.

im also thinking of picking up some old gamecube games, i mean if you havent played them before it would be as if its a wii release in a way.

i might get that new wario world and starfox adventures 2

The games mentioned above plus Gladius and Legend of Zelda: Four Swords Adventures.

The Prince of Persia Trilogy if you've missed it and of course LoZ the Wind Waker, The Four Swords Adventure I really like even a solo mode.

TimeSplitters: Future Perfect.

A nice singleplayer mode, with some missions to acccomplish.
Also a great multiplayer option, which you can play for loads and loads of hours
And some tasks you can complete.. I don't know the name. Like: "Kill 10 bots within 3 minutes". Get them all on gold, it's damn hard

Wow lots of games. Good response guys. To those that mentioned it I have Resi remake forgot to put that one in. Man I love nintendo loving people. You guys are some of the nicest people on here. Cheers for this thread staying awesomely clean. Anyways keep the games rollin, Obscure ones that are good I'll give a shot to. I going to town tommorrow to buy like 10 games cos they are so cheap. :)

Eternal Darkness - great game, full of mystery.

Animal Crossing - You play as a character and travel around a town and do stuff and collect items for your house, over the course of the time your house and village becomes bigger and you get to participate in various activities, great game, played it a lot of it myself.

Wind waker - awesome game, and great graphics. Good story and its fun finding out the puzzles

Mario kart DD - addictive mario kart racer thats fun to race with friends

havent heard Metal Gear Solid Twin Snakes (remake of ps1 mgs)

I do! I also think Tales in very overrated! (although, I picked it to give it another try).

I've also been looking for Eternal Darkness. If anyone finds it online for a decent price. Let me know.
