Well I went ahead and found some stuff anyway, Aug 98 issue of Nintendo power and I quote the fan mail
"I saw screen shots of SMRPG2 and could not believe them! The graphics are as good as South Park!

"You're kidding, right? You called the graphics in SMRPG2 a "2-D look in a 3-D world." I don't want Super-NES style games on the N64!

What are you thinking??? (yes literally 3 question marks) A 2-D painting? It looks like you ruined the graphics of Super Mario RPG 2 just for the sake of variety.
Or this preview of Turok 2
"At E3, we were among a select few journalists and industry insiders who were allowed a sneak peek at an early version of Turok 2. What we saw in Iguana Entertainment's heavily guarded suite blew us away. Imagine our delight, then, when we were invited to Iguana's headquarters for an exclusive, in-depth preview of the game-in-progress-"
And guess what, the coverage is uniformly positive, just like it was for every game previewed, like, ever.
