very nice list everybody (especially those with snes ranked 1) but somebody's list is conspicuously absent. i checked his profile and I saw hes been online since the creation of this thread.

maybe he is still working on it

1. PC for many reasons, especially for 1998 and Everquest.
2. MSX, got me into programming which ended me up with a great job.
3. PS4+PSVR, made me feel like I was back in 1998 again, so many great new experiences.
4. PS5+PSVR2, managed to drop my jaw to the floor again, can't get enough of driving around the Nordschleife in classic race cars in VR.
5. WiiU, Lego city undercover, Windwaker HD and Super Mario Maker made me feel like a kid again.
6. Switch, BotW, Odyssey and TotK, nuff said.
7. PS3, still the best multi media player, GT5 online had me instantly hooked, birth of Souls games.
8. PS2 just for the sheer quantity of quality games.
9. N64, felt like magic at the time
10. PS1 first console I bought myself, worth it alone for Wipeout 2097

Other consoles I (have) own(ed) DC, GC, XBox, X360, Series X, Wii, Intellivision, GB, PSP
And played on Atari, C64, Amiga 500, MSX 2, NES, SNES, Sega Genesis

Minus Computer/Steam/GOG/EGS/etc

1. Switch 1
2. Playstation 2
3. Super Nintendo
4. Gameboy Advance
5. Nintendo 3DS
6. Playstation Portable
7. Nintendo DS
8. Xbox Series
9. Playstation 3
10. Playstation 5

Hope this is ok but im going to rank my top 10 with half the systems I never even owned, just know that they have fantastic games.

#1. PC
#2 NS1
#3 Xbox 360
#4 PSX
#5 SNES
#6 PS2
#7 NDS
#8 NES
#9 SS
#10 PS4

My Top 2 are in order, but not the rest.
1. PS4: Despite a lot of shovel ware and medicority for being a super popular console, the sheer amount of good and great games on PS4 is staggering. And some you couldn't play anywhere else for a while.
2. Switch: Mountains of shovel ware and mediocrity, but Nintendo's best first-party lineup to date (even excluding ports and remakes) and a brilliant hybrid concept.
3-10. GameCube, 3DS, Xbox 360, PS5, Wii, PS3, DS, Xbox One
Honorable mentions: GBA, PS2 (still never owned a PS2 but had some fun on it at other people's houses)
Switch 2 will surely rank highly given its features, backwards compatibility, and all but guaranteed banger first-party library. Even Wii U had some strong first-party games.

Ranked after how much fun I got from them.

1. Nintendo DS 

Played so much stuff on this thing. Many unique experiences. The lite had battery stretching 25 hours. 

2.  Wii

Playing without needing my hands put together in a grip on a regular controller felt freeing. Best in ip releases for many of my favorite series. Except smash. Dislike brawl with passion. 

3. Playstation 3

Best standard console. Nothing really unique about it. But damn if it did not have banger games. 

4. GameCube

Only had like 4 games for this system for the longest time. Playing Smash and Mario Kart is still awesome with siblings on get togetherings. 

5. GBA

Bought a special version of this absolute gem of a system. A regular GBA with a backlit screen and built in rechargeable batteries. Still bring this along on trips.

6. Switch

Because this f*ucker is to large and short on playtime per charge. One cannot deny the ridiculous large library on the thing however, even if I mostly play tetris and...:

7. SNES

-games on it. The definition of classic. Nes is mostly old junk (sorry), but the 16 bit games hold up very well. Siple but effective.

8. Playstation 5 

Would probably be placed higher if I had more time to spend playing. Playstations best controller by far imo. Great system over all.

9. Dreamcast

The best "failed" system. Almost everything released on this thing is good. Not something I can say about:

10. Playstation 2

Where most things I tried was not my type of game. Got one because it was cheep at the end of its life and I wanted something to play after moving out of my parents house. Bought several paper bags full of games. Played uncounted hours on it, but liked around five games. Never liked the system really, felt like such a downgrade from the family's GameCube. But I played and replayed Resident Evil 4 enough to land the system on the list. 

I dont have 10 different systems but here it is anyway.

1.ps2
2.ps1
3.ps4
4.ps3
5.snes
6.xbox
7.gamecube
8.xbox360
9. Ps5(sucks monkey balls)

Atari 2600, NES, Genesis, SNES, N64, PS1, Dreamcast, PS2, 360, Wii.

My reaction to seeing angrypoolman again. I feel like I was transported to 2010. Luckily, I graduated from high school a long time ago.

I don't really 'like' rating systems because I tend to play plentiful old games on 'new' systems. Also, how would it work if a game is multiplatform?
If I had to rate what I played, and went by generation and exclusiveness, it would be something like this (Keep in mind I don't have ten systems so the latter half will be very wonky.):

1. DS (No system boasts quality and variety as the DS. Want to play a fantasy game? You can. Want to play a game where you are training your brain? You can. And both are worth playing.)
2. SNES (Best balance between modern and primitive. It improves on most of NES originals, although the RPGs really make it shine.)
3. NES (The most original Nintendo console. If not for its primativeness, I would consider it the best of all time.)
4. Genesis (This is like SNES but more raw. Think Gun N Rose versus something like Bon Jovi.)
5. PS1 (Easily the best Sony system. The only one I really like, honestly.)
6. Switch (This one just feels like I enjoy the ports more than its original games, but it is Nintendo's best modern system.)
7. 3DS (I like this one mostly for the RPGs
8. Xbox 360 (A lot of good titles here. The last time we had a lot of original and good AAA titles. After this, they became much rarer with time.)
8.5 PS3 (Too similar to Xbox 360 to justify its own spot. But what it has over 360 is the JRPGs.)
9. Gamecube (This is really only here because I like Pikmin and Melee.)
10. PS2 (I suppose. I haven't really played too much of this one. But anything below this system is lame. Not a fan of N64, the other Xboxes, PS4/5. GBA doesn't have too many exclusives I like. Gameboy is too primitive for me.)
