Mario and Luigi: Partners in Time is a great RPG
Graphics are great there nice and clear and colourful they are definitely better than Superstar Saga Graphics but you would expect that as it is a sequel all the worlds are bright and detailed and are very well animated the characters look great and detailed overall there some of the best Graphics on the Nintendo DS.
Gameplay is great it has improved there are more moves more stuff to do but it is the same to start a fight and get extra damage before you start you either jump on the enemy or walk into them in this it does play differently as there is baby Mario and Luigi as well as Mario and Luigi the baby's are just usually on your back but when a fight starts like in the other game you have shells they stand on the shells and they do more damage and they help with puzzles and some parts you just play as them and like in the other one you have different items for different stuff like healing items others the cure you from poison and others that give you different abilities overall the gameplay has improved with some great new additions new moves and just more stuff to do.
Story is good maybe not as good as the other ones it still funny with some great new characters and some weird new enemies.
Replay well there is to me there was loads of replay as i played it 3 times there is stuff to collect and other stuff to do but if you dont want to play it again there isn't much else to do but the game is about 15 to 25 hours long maybe a bit longer if you dont know where to go but there is some replay.
The Good
Great Graphics/Great Gameplay/Great New Additions/New Moves/Good Story/15 to 25 Hours long.
The Bad
Jumping can sometimes be awkward.
