When to worry about endianness?

I have seen countless references about endianness and what it means. I got no problems about that... However, my coding project is a simple game to run on linux and windows, on standard "gamer" hardware. Do I need to worry about endianness in this case? When should I need to worry about it? My code is simple C and SDL+GL, the only complex data are basic media files (png+wav+xm) and the game data is mostly strings, integer booleans (for flags and such) and static-sized arrays. So far no user has had issues, so I am wondering if adding checks is necessary (will be done later, but there are more urgent issues IMO).

I believe Power PC has the opposite endianness of the Intel boards. Might be able to have a routine that sets the endianness dependant on the architecture? I'm not sure if you can actually tell what the hardware architecture is in code...maybe someone smarter then me does know the answer to that question.

Now in reference to your statement "standard" Gamer H/W, I would say typically you're going to look at Consumer Off the Shelf solutions are really what most any Standard Gamer is using, so you're almost going to for sure get the same endian across the board. I'm sure someone will disagree with me but that's my $.02

Ha...I just noticed on the right there is a link that is showing up related to the suggestion I had above.
