I bought a 360 elite (after my originals had RRoD and were binned) to play Alan Wake back in the day, nothing else interested me that I couldn't play on PS3. I also bought a Switch to play Breath of The Wild alone, ended up liking Fire Eblem Three Houses more but BoTW was the one that got me in the door. 

The only thing on PS5/XSX that is released right now that would move me to the systems is Baldurs Gate 3. With GTA6 coming it's a different story. If my PS4 PRO wasn't overheating with newer cross gen games and I wasn't forced to, Id be upgrading for Baldurs Gate 3 alone with the other games being a nice plus. 

Anyone else foolish enough to buy a console based on one or two exclusives?

I guess technically I did buy the PS2 back in the day just so I could play Final Fantasy X, but I was well aware even at that point that I would eventually get a lot of other titles for it as well. Still, the initial reason to get the console was Final Fantasy X.

no, need other stuff to get to make a purchase

Nope. There were always multiple games I want in every console I owned.

Yes.

In fact, just about all consoles I’ve ever bought were for a single game. Before that, when I was a kid asking for video game systems, those were because of one game as well.

But I expect consoles to have other games I want. Sometimes this doesn’t end up being the case and I end up really only playing a lot of that one game and minimal time on others: Gamecube (Animal Crossing), Wii U (Xenoblade Chronicles X), and PS3 (Assassin’s Creed 2*) are the main examples.

Actually, I bought PS3 specifically for FF13, not Assassin’s Creed 2. I enjoyed the first 20 hours or so of FF13, despite feeling some things were missing over previous games (namely towns). But then I reached this area where the story abruptly stopped, it was opened up, but didn’t have much of anything interesting. It was kind of jarring to the experience, so I figured “Probably a good time for a break from this game and come back when I’m ready for this style of game,” and I never played it again… perhaps I will in the future.

But regardless, Assassin’s Creed 2 was a game I picked up, finding the idea of exploring Renaissance era Florence to be interesting. I found I quite enjoyed that one, and ended up playing it a lot.

How many titles would you say you'd need. And would future titles that are promised sway you to a decision?

How many?

Hey. Reply to my post in The Witcher 3 thread ya Bum. 😉

Man you really do love Xenoblade. I can't understand the love for it though, I have Xenoblade X Chronicles on cart for my Switch but every time I try to get into it, I feel as if the game is playing itself, I eventually fall off cause of that, it's not quite Overlord Unicorn but there is little agency in combat. 

I bought a PS3 solely for Final Fantasy Versus XIII.

Mario Odyssey in the Jan 2017 presentation was enough to convince me to purchase NSW at launch. Put 230hr into that game.

I purchased an Xbox One X for PUB G. I did end up with a large library for it later on.
