Well, there are many games that allow for multiplay options. I don't know where a master list might exist, but here are a few of the more fun multiplayer games for DS:
1. Mario Kart
2. Metroid Prime Hunters
3. Advance Warsays of Ruin
4. Advance Warsual Strike
5. Jump Ultimate Stars
6. Daigasso Band Brothers
7. Geometry Wars Galaxies
8. Speed Racer
9. Jet Impulse
10. Final Fantasy Crystal Chronicles Ring of Fates
11. Soma Bringer
Every single one of these is a great multiplay game. Most of these games are English, but the ones that are Japanese have English patches for them. That is, except for Jet Impulse, but you can still play it since it isn't too text-intensive. If you search the forums here, you will find that there are many other threads that have been entered discussing this very topic, so you can get more ideas there. Hope this helps.
Human vision is logarithmic, it's not linear. And nits doesn't tell the whole story of perceived brightness. OLED'S look brighter then LCD's even when both are set to the same nit values because of the higher contrast ratio on OLED's
"And nits doesn't tell the whole story of perceived brightness" it's not about perceived brightness it's about all HDR content in TV and movies being mastered for 1000 nits so it doesn't look right with anything lower, it's also about dynamic range
OLED's can get away with a lower peak brightness and still provide punchy HDR because of their contrast ratio. Like I said human vision is logarithmic. The higher the peak brightness the diminishing returns in perceived brightness.
@The Real Jdbye Oleds hit around 750 nits nowadays. The difference between a 1000 nit and a 750 nit isn't huge. It's only about a 4% increase in perceived brightness. Not huge at all. You'll need at least 2000 nit displays to notice a bigger difference.
