How does everyone feel about including collectible items to CDDA? Some with eventual uses perhaps?
Some ideas:
Deck of Cards:
54 total cards to collect. Once all are collected and combined, (a)ctivating the deck of cards will allow you to play solitare for a morale boost.
Postcards:
Finally a use for town names?
Novelty Lighters:
Just for fun.
EDIT:: Thought of another good one:
Tarot Cards - 78 total cards that when combined into a deck and (a)ctivated will have a chance of informing you about certain “invisible” effects. ( Infection, Radiation Poisoning, etc. )
