Here's a collection of what OMG Nintendo think are probably the nine best turn-based strategy games (defined broadly) that you can play on you DS. So, really, the best DS and GBA titles in the strategy genre without significant real-time elements.
Pretty good list. Odd though how they don't mention the new Final Fantasy Tactics A2. Also even though it's not true turn based the Izuna games are great. They play more like a free roaming hack and slash however it's got a turn based engine under the hood. For each action you make be it taking a step, attack, using a item all the enemies in the field get a action. It's a great game and the 2nd one was just released and I'm having alot of fun with it.
