SPORTS ILLUSTRATED PRO FOOTBALL is the predecessor of the later SPORTS ILLUSTRATED PAYDIRT FOOTBALL GAME. With minor alterations it can also be played with the charts from the later game. Each game includes a set of team charts, one for each of the pro teams of the given season. The charts reflect the success of the team in running a variety of offensive and defensive plays. It is one of the most playable sports simulations ever created yet still manages to produce realistic results.
I've found that this edition is the most difficult to acquire. I think there was only a short print run because they decided to change the name of the game to "Paydirt" later that year. It features a great action shot of a Steelers vs. Dolphins game.
This particular copy is still sealed in the shrinkwrap. Even has the original $8.99 "Value Giant" price sticker still affixed. The game box is in EXCELLENT condition. It has a few creases on the lid and bottom near the corners from stacking. Otherwise it's in great shape with nice corners and bright colors. I would grade it a 8 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. Charts will have at worst some dented corners from shuffling around in the box. Perhaps some very light handling creases to the instructions or other minor flaws with the game parts. Boxes will have only very minor shelf wear. EXCELLENT (7-8): The game has seen some use but it was obviously well taken care of. Charts may have denting to the corners, perhaps a few may have light stains or other very light handling wear but the vast majority will be close to flawless. Game parts might have some light handling creases or other signs of careful use. Board might have just a hint of rubbing. Boxes will have light rubbing to the artwork or perhaps some minor dishing. VERY GOOD (5-6): The game was not especially well cared for but it still has faired pretty well. Charts will have light handling creases or light stains. Perhaps a couple may have a few stray pen marks or a small edge tear. All chart results will be fully readable. Other 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. Charts will show moderate to heavy use and many will be yellowed, stained, creased, torn or written on. All card results will be fully readable. Other 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. Charts are heavily worn and some are badly damaged. Game will be missing parts (these will be noted). Box will have serious damage and may be missing aprons or badly torn.
