I`m surprised no one has mentioned the Heroes of Might & Magic series yet. Heroes V was a good turn-based RPG (a bit difficult, patch fixed that though) and it has a couple of expansions out now.

I`m not sure if Knights of the Old Republic would count, it did have some tactical elements to it though, the way you have to manage the members of your party and all and it was certainly turn-based.

You type them in while playing.

I'm not exactly sure as to what the question is here...

Are you asking what our favourite DS game is?

The first StarCraft novel, Liberty's Crusade, is hands down the best novel based on a video game.

It's essentially the entire plot of the Terran campaign in novel format with a new protagonist. Everything else that's been translated into a novel is just garbage compared to that.

Lego Rockband? Seriously?

2D Side-scrollers, any RPG games and some turn-based strategy games. RPGs are really what the DS does best.

Some GBA games use a battery to save data. The battery for the game is probably dead. If that game doesn't use a battery, it's probably a problem with the game chip itselfSoulreavercross
