I am still relatively new to the Dreamcast, its been less than a year since I owned one. I lurked around the forums for while before I joined. I really appreciate all the helpful info Dreamcast-Talk has, it helped me with deciding on what accessories to get. All of my stuff is used aside from the Fishing controller, Sega Bass Fishing and Sega Marine Fishing. Most of my stuff comes from the local used game shops, one of them is particularly useful since they sell imports and I developed a good relationship with the owner. Sorry for the poor quality of my photos, I am bad at photography.
Edit: I just brought House of the Dead 2 today.
