If you don't like it, don't pay it. I mean its pretty simple. I've been gold since original X-box so obviously I think its worth it. Everyone I know that has it uses and enjoys it. It doesn't really limit the system outside of online play if you don't have it. I think people have misconceptions that you aren't allowed to do anything with Silver which really isn't true.
Odd about inflation though, if a new video game has only gone up from about $50 to $60 since the mid-eighties, that's not bad in general for video game inflation. New consoles cost about the same generation to generation.
