With an 8 GB iPhone 3GS, I keep my phone pretty much filled to the gills with games so space is a precious commodity. But lately I've noticed that some games are starting to have "small" file sizes for intial downloads then as you progress through the game it downloads levels without asking (which you thought were part of the initial download and these are not add on packs). Both Shark Dash and Mega Run are two culprits. Shark Dash is a 33.6 MB download (can't remember the installed size but think it was still under 50 MB). But as you progress, the file size grows and grows and it ended up being over 100 MBs in size. Same with Mega Run....and that game seems to take longer times to load the additional levels. Anyway, I thought it was kind of deceiving and a little annoying. I know not everyone has space concerns. But is this going to become a trend?
