I have collected a lot of things over the years, so I am a collector at heart
Lol ... the Collectibles are really only little bits of pixelated art (sometimes animated - ooooo)
For me also, because I have a need to complete sets, I am driven to acquire one of each ... and some are more desirable to me than others because of my likes, interests, and nostalgia and contest achievements ... and some are just so plain purty ... like the Sakura
The ones that I love and value the most however are the ones gifted to me by friends on the forum ... those ones I keep forever
PS ... I also love gifting Collectibles and giving away in contests or giveaways
