Mattel produced a few different versions of Rocket Hockey during the 70's and 80's. They are both the exact same game. The only difference is that the 2nd version is endorsed by Wane Gretzky. The original came out in 1978, the Gretzky version the following year.
The game parts are in VERY GOOD condition. I have carefully inventoried and inspected the game parts and everything has been accounted for with the exception of the little plastic piece that holds the "puck" steady while you are winding it up. The game works fine without this though. You just need to be careful it doesn't fly off and smash a window or something.... The game instructions have some light handling wear and there is some general wear to the game from normal use. Overall I would grade the game parts 6 on a 10 scale (see condition guide below).
The game box is in VERY GOOD condition. There is a tear in the cover art where it appears that something was removed and the box bottom has some staining. I would grade it a 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 handling creases to the instructions or other minor flaws with the game parts. 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. Game parts might have some light handling creases or other signs of careful use. Board might have just a hint of color loss or dented corners. Boxes will have light rubbing to the artwork or perhaps some minor dishing or a very light stain. VERY GOOD (5-6): The game was not especially well cared for but it still has faired pretty well. Game parts will show obvious use but nothing will be torn, badly stained or have any serious damage. Box may have some rubbing, light staining, dishing, 1 or 2 neatly split corners, minor writing and/or a few pieces of tape. 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. Game parts show considerable use but the game is complete with all parts in usable condition. Box may have staining, writing, split corners, dishing 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 will be missing parts (these will be noted). Box will have serious damage and may be missing aprons or badly torn.
