Diablo III: Eternal Collection

Diablo III: Eternal Collection surprised me by running better on Switch than I expected from a game this dense with particle effects on screen at once. Four-player online co-op drops you straight into a dungeon crawl with friends, and unlike Diablo IV, which I never finished, this one respects a shorter session. Seasons keep bringing people back with fresh characters and altered rules, which matters for a game without crossplay to prop up its population. Drop-in runs take twenty minutes and don't demand a build guide to enjoy. It's older, and it shows in the character models, but the loot loop still works exactly as well as it did at launch. A genuinely good pick for a casual co-op grind without Monster Hunter's commitment.

I started Diablo IV on PS5 and never finished it, but Diablo III on Switch is a different proposition entirely. The portability changes the loop. The couch co-op with up to four players sharing a screen while building out loot synergies works better than it has any right to in handheld-adjacent play. It missed the top ten because the accessibility bar is genuinely higher here. Newcomers to the genre will spend a while figuring out what is happening, and the screen can get cluttered fast with multiple players. For an experienced group wanting the deepest local co-op loot experience on Switch, nothing else on this list comes close.

My group has played a lot of Helldivers 2 on PS5, and what I noticed moving to Diablo III on Switch with a friend was how much more generous the co-op loop felt. Everything scales, loot drops for both players individually, and you can be wildly different character builds without one person carrying the other. The Switch port has held up well since launch, which is not something you can say about every third-party Switch release. If your duo wants something with real mechanical depth and a reason to keep coming back beyond the campaign, this is the answer on Switch.

Diablo III on Switch is older than most of the games on this list. That is basically the only thing working against it. Everything else, the four-player loot loop, the build variety across classes, the ability to pick up and play for 30 minutes without losing progress, still holds up. I started Diablo IV on PS5 and did not finish it, but I have never had the same issue with Diablo III. The feedback loop is tighter and the sessions feel complete even at short lengths. In handheld mode on a commute or docked for a couch session, it works either way. For action RPG co-op on Switch, this remains the clearest recommendation.

My LAN group has a rule: if a game can be explained in thirty seconds, it stays in rotation. Diablo III qualifies. Pick a class, kill demons, chase loot, upgrade your skills, repeat. Four players local on a single Switch, or online, the loop never gets old because the gear chase keeps reshaping how your character feels. Seven classes with genuinely different playstyles mean nobody is doing the same thing as the person next to them. The Switch version holds up in handheld and docked mode alike. If you want one co-op RPG that works for a full group with zero friction, this is the one you buy first.

Diablo III: Eternal Collection earns #2 because its entire design revolves around shared progression over the internet. Groups pick complementary classes, tear through dungeons, and chase better gear season after season. The Switch version offers smooth online play and includes every expansion, so there's always another difficulty tier or build idea to try. For loot-driven groups seeking infinite replayability, it's a long-term staple.

The most complete action-RPG package on Switch for four players sharing one screen: lengthy campaigns, deep builds, seasons, and endless loot hunts. Steady performance and couch-friendly drop-in make it easy to run a few rifts or lose a weekend to Greater Rift pushes. Narrowly misses the top 10 because local camera zoom and dense menus can be tough to parse from the couch, especially in handheld mode.
