The WORLD CHAMPIONSHIP series of games was Mattel's attempt to capitalize on the 2nd generation of electronic handhelds. These were 2-player tabletop models with improved graphics and much more advanced game play than the 1st generation of games. No more dots and dashes to represent the players. These games had symbols that were actually recognizable as human beings! They were in may ways based on the Mattel Intellivision Video Game system cartidges that were popular at the time. Unfortunately there were a lot of problems with the games. Oftentimes the displays did not function properly and the battery connectors were easily damaged. And to top it off sales were not great. Too bad because these games really are great fun to play.
The game console is in VERY GOOD condition. All buttons, switches and sounds work. The movement buttons work very well but the play selection buttons sometimes needed to be pressed a couple times before they kicked in. This shouldn't affect your ability to play the game. Battery cover is present and battery compartment is reasonably clean but there is some corrosion. Display screen works fine. I would grade it 5 on a 10 scale (see condition guide below).
The game parts are overall in VERY GOOD-EXCELLENT condition. The instructions have some light handling wear. Overall I would grade them 6-7 on a 10 scale (see condition guide below).
Box is in VERY GOOD condition overall. It has general shelf wear including some light stains on the back and some tape on the back where the previous owner taped the box shut. I would grade it 5 on a 10 scale (see condition guide below).
MINT (10): I will only give this grade to brand new, unused items. NEAR MINT (9): Shows virtually no use. Seldom if ever played. Perhaps some very light scuffing to the back of the console. Packing materials, instructions and other paperwork will show almost no signs of handling. Boxes will have only the slightest hint of shelf wear. EXCELLENT (7-8): The game has seen some use but it was obviously well taken care of. Console will have more noticable scuffing, maybe light wear visible on the screen or in the button area. Paperwork may have some light handling creases. Packing materials may have a light stain or small chips but will be intact and free cracking. Boxes will have light rubbing to the artwork, perhaps some minor creasing, small tears on the flaps or a small stain. VERY GOOD (5-6): The game was not especially well cared for but it still has faired pretty well. Some obvious scuffing from play but all labels intact and readable. Perhaps a very minor chip on the edge. Paperwork will have some handling creases and may be lightly stained or have some writing. Original packing materials may be damaged but will be intact. Box will have some rubbing, light staining, creasing, small tears, minor writing and/or a few pieces of tape. Might have a missing flap. No major structural damage and artwork will still be generally attractive. GOOD (3-4): Obviously no care was taken with the game but it is still playable as is. Console will show heavy use but will not be seriously damaged in any way. May have a few burnt out LED but is still playable as is. Paperwork will have heavy handling wear and may be torn and taped back together. Box may have staining, writing, heavy creases, tears and/or other structural damage but it will be intact and still usable. POOR (1-2): Only suitable to fill a space in your collection. Game may be seriously damaged or inoperable. Paperwork will be badly torn. Box will have major damage.
