@rohan1992 The easy/medium/hard isn't just telling you how hard the achievement is. You can only get the medium achievements on all-star of HoF. You can only get the hard achievements on HoF. But you can get the easy ones on any difficulty. So you probably were not on a high enough D-level.
Well, what you have to do on HoF is play smart. You have to run the football even if you are only getting a yard per carry, it is important to stay balanced so the defense isn't pass heavy. And if its 4th down, unless it is a reasonable spot and distance just punt it, because you cant afford to give the opponent a short field. Same thing when you score, don't use the onside kick a lot, because you don't usually get it and you don't want to give them a short field.
It is possible to take returns quite far, even all the way for a touchdown. But, I'm glad that it is difficult, 'cause it would not be any fun if you always returned it for a touchdown.
A guide to play ten: When you run play ten wait for the running back to come out of the backfield and usually he isn't guarded and you can get a big gain on the play. On defense be the person guarding the running back and if you guard him well the QB will throw to a WR and you will usually get a interception.
You can make the ball move faster just by holding the mouse button down longer. And as for interceptions happening too much on the more difficult levels, you just have to be careful not to throw too many jump balls.
You guys are asking a lot. Yeah it doesn't have all the cool features as madden nfl. But this is most likely the best football game I have ever seen online.
