Of those 3DO games you listed, they either can be found on another system (Road Rash, Gex, Myst) or they're not really good/pale in comparison to N64 exclusives. The N64 is pretty low on my list of consoles (2nd to last if we exclude handhelds), but the 3DO doesn't even warrant an appearance.
A lot of those games on 3DO that are on other systems, the other systems got inferior ports. This is pretty common knowledge, so there isn't much point in mentioning that unless you just want to make the Saturn and PS1 look bad. The 3DO had a good mature library that also tended to give gamers a pc like gaming experience. And honestly there is nothing on N64 that can evenly match something like Wing Commander III, Star Control II, Return Fire, Shockwave 2, Road Rash, Need for Speed, Primal Rage, Panzer General, or Super SF2 Turbo. And I was just naming stuff off the top of my head that I owned prior. I could grab a list of all the titles released and tack on even more to the above list.
And when we get down to it, this comparison about game libraries isn't about 3DO, PS1, Saturn, PC, and N64. Its only about comparing the 3DO's total library to the N64's, and which one I'd rather have more, and why. By all accounts the N64 game library should have blown the 3DO's away completely. But it didn't. It didn't even come close. Nintendo was too busy trying to appeal to kids still and the casual uninformed gamers or their parents that bought something because it said "Nintendo" on the box, because Nintendo always meant quality, amarite?
The N64 shined most in its cartoon'ish 3d adventure titles like Super Mario 64 and the Zelda games, which yeah, the 3DO doesn't have, but I also don't like Super Mario 64 or the 3d Zelda titles, so no f*cks are given. If those kinda games are what floats your boat, then I'd def not recommend a 3DO. When the N64 was out I was already at a point in my life where I outgrew Mario and wanted something that felt more mature then that or crap like Pokemon Snap.
Given a majority of the N64 stuff is trash, inferior ports of games on other systems also, choppy FPS titles, or sports games, it leaves very little as far as original compelling content goes, outside of Treasure, RARE, and Nintendo's titles.
And to throw this back at you, just for the sake of argument in favor of a systems merit based on ports being on other systems, most of the good games on N64 not made by Nintendo are done way better on other systems or PC. Rouge Squadron on PC, along with Shadow of the Empire and Episode 1 Racer make the N64 versions look like clown shoes. Quake 1? Better on PC and Saturn. Quake 2? Better on PC. Resident Evil 2, same deal, its on DC, GC, and PC and are worlds better on those other formats.
MK Trilogy? Better on PC and PS1. Biofreaks and WarGods? Better on PC. Gauntlet Legends? Better on DC. MK4? Better on PC and DC. Sf Rush 2049? Better on PC, GC, Xbox, and DC. Ogre Battle? Better on PS1. Starcraft? Better on PC. Vigilante 8 2nd Offense? Better on Dreamcast. Turok 1 and 2? Better on Pc. Hexen? Better on PC. Winback? Better on PS2. Wipeout? Better on PC and PS1. I mean I could go on and on, but you get the idea.
Thankfully the 3DO didn't suffer that kinda fate. The games on it that are on PS1 and Saturn are more often then not better on 3DO.
