Potential is not the same as power. Most of the time the most powerful console of the generation loses against a weaker competitor (N64 lost against the PS1, XBox and GC lost against the PS2, PS3 and 360 lost against the Wii, Sega Game Gear lost against the Game Boy, the PSP lost against the DS...).The Switch is selling a lot through practically 1st party effords alone, with very few 3rd party heavy hitters outside Just Dance, Monster Hunter and Minecraft. Until the PS5/XBoxX manage to catch up (which is going to take years), the Switch is going to be the biggest platform for console gaming by far, and yet we've seen little attention from most 3rd parties.
It's pretty crazy how insanely successful Switch is (will at worst be 3rd best selling system ever) given that MH Rise is literally the very first entirely third party AAA game that is actually built for the Switch instead of being some really old port or arriving a couple years late (DQXI) or somewhat old downgrade from current home systems. Literally, the only one, and Switch just passed its fourth birthday! Switch has blown away the competition and has a great library despite the fact that the big games in the library are essentially all first party and indies. Imagine if third parties actually put together a team or two each to build AAA games for a system that will very soon be over 100 million systems sold and is by far the hottest thing in the industry.
