So recently i've been thinking about the advantages of a game with tile based structure and vice versa. Especially In platformers.
For anyone unfamiliar with tiles, read about it here.
So some advantages of tile based game:
Reusable assets, which means smaller file size.
Easier to handle collision detection, since you will mostly be dealing with blocks and simple slopes.
Everything has a similar scale(player is usally one or two tiles height and most other stuff one) allowing for tight platforming.
Easier to make a level editor for others to use
Advantages of non tile based platformer:
Objects aren't strictly placed in a grid like with tiles
Levels can have much more of an natural structure and crazy slopes, such as the slopes in fancy pants.
Arbitrary rotation and scale of objects in the game
Great usage of the timeline in flash to load stuff and do other things if done properly
So what do you think? I know lot of you who have done platformer here have went with non tile based. What do you think is better and why? I will maybe list cons later but i'm almost falling asleep 
I don't really have anybody to talk about this kinda stuff
