The Base Set can be identified by not having a "95" symbol on the cards. Donruss hit the market with Red Zone in 1995 with the fist CCG based on the NFL. In addition to having an NFL player on each card and numbers on the side of the card to represent his ability, each card had a series of numbers and other information on the bottom, as well as an offensive play in the upper left hand corner and a defensive play in the upper right. You "drafted" a team of players and the rest of your cards formed your deck. After the kickoff, each player chose from one of eight plays (offensive or defensive). After cross-referencing the plays on a chart, each player would draw a card from their deck and colors on those cards would determine the final result of the play, usually a yardage total or an incomplete pass. Play followed the normal rules of football, with 30 plays per quarter. Special cards represented more unusual plays like injuries, fumbles, and so on. The game had some value to football fans, but is tedious and repetitive to play. The actual players you sued to play rarely made a difference. Once you had players with higher ratings, there was never a reason to use lower rated players.
