Nintendo should let these guy make a new F-Zero.
...
implying that this 5 people team has shown, with the release of the FAST Racing NEO, that they would be able to develop a proper F-Zero game. NEO's handling system was very limited, the track design uninteresting.
If you look at the last 3D F-Zero game, GX, you will find a game that gives the player an overwhelming control over their ship. The handling mechanics are complex and the player has the ability to turn "on a dime". This directly affects the track design. You can put the player in those crazy tracks that F-Zero is know for, as he/she has the tools to take even the sharpest of turns.
FAST Racing NEO is the opposite. Unlike F-Zero, you only have a couple of turn options, and you absolutely can't turn "on a dime". In NEO, when going at high speeds, you have to anticipate even the easiest of turns, if you want to avoid touching the rails. The ability that the player has to turn the ship is very limited, and this is reflected in the tracks, which have long and smooth turns to give the player time to take the turn.
Even if we ignored that shinen is a 5 people (or so) team, thinking that these guys could make a new F-Zero is just an assumption because they have never done anything like it.
Making a game with an awesome sense of speed is simply not enough.
