They do, but only a fraction of the time and resources of a game built from the ground up. The list was being offered as evidence of how many fully-developed games Nintendo could produce in a certain period (I think 2 years), not how many games + ports.

Again, fact is that even ports/remastered take time and resources when we talk about output and productivity, so thats why they count also. That list is offered as evidence of output and productivity of 1st/2nd party games for Switch in certain time period, not just about new and fully-developed games. Also that list is not complete, we don't know what else unannounced games we could have in next 9-10 months.

1) I'm not sure why you are reiterating this point, as I've already agreed that ports take resources in the post that you are quoting...

2) Go Back and read Zorg's original comment, he says:

"Factor in that they likely have a few more unannounced games for later this year/early next year and you're looking at 25-30 1st/2nd party games in the first 2 years."

He says nothing of ports! Let's remember that these comments are made in the context of Nintendo's future development output. So what that comment says to me is that list is indicative of what we can expect from Nintendo going forward. If we assume that a port takes around 10% of the resources of a fully fledged game and that ports make up around, say 40% of that list, then the 25-30 games becomes 16-19 games over 2 years - which is short of Nintendo's aim of a game a month.

On a slightly different note, I feel Nintendo needs not only to produce a game a month, but a BIG game a month. They can supplement with smaller games like Sushi Strikers, 1-2 Switch etc. but most people want more meaty experiences and without the strong support of most 3rd party devs Nintendo really need to ramp up their big project output. Either way I think that the Switch will be successful, is just a case of how successful...
