At my local Value Village there area bunch of Master System games. All of them have the box and only one or two do not have manuals.
There are some common games like R-type, Afterburner, and a two game combo cart whose name escapes me at the moment, but there's also some harder to find games like SpellCaster and Joe Montana Football. VV is selling them in bundles of two for $10 each.
I don't know if blue tags will be half off tomorrow but I don't think the games will be there longer than a day or two regardless.
What do you think? Should I take a chance?
