im gonna sift through flashpoint, but at least from memory, i remember all the flash games for foster's home for imaginary friends being really fun, the billy and mandy ones were solid, that camp lazlo wagon game you showed also rings a bell. now that i think about it, i played ALOT of flash games as a kid, way more than i thought i did, and i played them on any cartoon site i could. nickelodeon, i remember the fairly oddparents games, a few for el tigre, for disney there were a TON of phineas and ferb games, games for various sitcoms like suite life on deck and wizards of waverly place, a few emperor's new school games, i also played a bunch of nick jr/noggin and playhouse disney stuff as well. i've been wondering if there was a way to play most of these old games, so i'm glad i saw this video! def gonna go on a nostalgia binge soon edit: i also remember playing alot of 3d games as well. i know some of them were from 3D Groove, but there were a bunch of others that aren't listed on the lost media wiki so i assume they are based in some other 3d engine or something like that
edit 2: oh okay so i just checked flashpoint and they have a bunch of non-flash internet games preserved as well! for example, 'Phineas and Ferb in the Transport-inators of Doooom!' was made in unity, and it seems like they also have the 3d groove games i mentioned above
