The problem with this question is the usual one: if you were running NEC at the time, what you would have been able to bring out would still have been limited by what you could license. It's not right to treat it as NEC making a mistake in not bringing out some game that could have made the system more popular--it may have been out of NEC's control.
It might be more insightful to ask "what games would you have brought out to make the system more popular, that NEC actually had access to".
There is already a recent thread for that. This is simply a fun twist on the usual "which PCE games did you want over here" threads.
Exactly. This thread is not supposed to be a hard-thinking 'What should NEC have done differently' thread. It's not exactly, but it's kind of a twist on the 'You're stuck on a desert island with a TV, a Turbo-Grafx-16 w/Turbo CD, and 139 games (and a reliable power supply
), which 139 games would you want?' question. The whole point is to create a stellar TurboGrafx-16 library of 139 games. (A minimum of 60 must be HuCard games.) And this library should not simply be your exact personal favorite 139 games, but rather a somewhat reasonable mixture of genres from what was available. (In other words, your list probably shouldn't be 60 shoot-'em-ups, 40 RPGs, 30 platformers, 5 digital comics, 4 puzzle games, and no sports games. :-" )
