ok, this was very time-wasting but somewhat worth it,
In Olympus Colosium (KH:recoded) i replayed the episode and chose 30 layers, i then for every floor, smashed every blox and kiiled every heartless. The max score is: 242150, the feeling of satisfaction if you can do this is immense. but like all games you don't get an achievement or anything for it.
also, doing (attempting), in Final Fantasy 12 dustia lvl ups, which work like this:
1.as soon as you are told by Old Dalan to get the sunstone from the giza plains head to nalbina foretress, killing stocks of wolves.
2. the merchent next to the gate crystal sells phenix downs, sell your wolf pelts and by as many as possible (phenix downs).
3. head to the dalmasca westersand. do not go into the shimmering corridor (refer to map).
4. knock out your own health so you are less than 10% of max health, then head into the shimmering corridor
5.(must have wait set as battle thing NOT active) a dustia will spawn, as it is undead use a phenix down on it.
6. this part is crucial, if it drops loot try to pick it up BUT YOU MUST LEAVE THE SHIMMERING CORRIDOR BEFORE THE EXP AND LP COME UP ON SCREEN!!!
7. repeat steps 5-6 until you run out of phenix downs.
8. repeat all steps from step 2, you can sell the loot to the merchent for 500 gil.
Dusti gives about 850 exp and 3 LP
