How to start with CE

[CrossSleet]

I didn't even think about buying items to sell them for more money later, can you do this?
Anyway, thanks for replies. It's still big problem for me. For startes i was thinking just about buying nice CE for games i think i like (Tales of Symphonia, Dark Souls etc.) but now because of this forum i see people are focused on all franchise... i don't think i like litographs or arts or items like that (figures and artbooks maybe).
Does collection with only games (standard and CE) counts? Even if it's not rare presskits or figures.
Today i preordered Dark Souls 2 black armour edition with steelbook (didn't want figure because i think its ugly...)- does it counts ?

(offtop) I really want Bishoujo Liara and Femshep from ME series but dont see this anywhere....
Generally i wanted to focus on gameroom (my wife is a gamer too) because we have 4 consoles and 2 tv but no comfortable place but i think CE are nice too.
