I was just browsing through the 40+ appearances of Solid Snake in games and felt Little Big Planet 2's inclusion on the list seemed a bit odd because I don't remember him being in it or even how he could be in it. Then I remembered all of those costume packs Sony sold. Sure enough, LBP2 has 84 characters associated with it, when really it only has Sackboy in it.
I guess an argument could be made for that in a vacuum, but what about when it happens in other situations? Ryu Hayabusa's armor is available in Halo 3's multiplayer. Kasumi's outfit is available in the Super Swing Golf games for character Arin, as well as in Fatal Frame II as an alternate costume for Mio Amakura. All the parts for KOS-MOS are available in Soul Calibur III to create her in Create-a-fighter mode. Additionally, Solid Snake can wear Altair's outfit in MGS4 if I recall correctly.
Does the appearance of a recognizable costume count as an appearance by the character? I'm inclined to say "no" in all cases, but it seems like many people have said "yes" in a lot of situations as well. I'm not sure if I should be removing links or not when I see them. Is there already a policy in place about this that I wasn't able to locate?
