Just not AAA, but there hasn't been that many AAA UE5 games in general yet. Depending on how you classify games like Wukong, Stalker 2 and Hellblade 2 then the only AAA UE5 game at all might be Fortnite. Now that I think about it even upcoming UE5 AAA games are sparse in the immediate future? 2025 might only have that Marvel game that you would fully classify as being AAA? The other projects known to (or highly speculated to us UE5) that are AAA I believe are much further down the pipeline currently.
The Matrix and those user created demos I believe would be only "content" that use UE5 currently in a somewhat contemporary open city environment with faster than foot traversal akin to Cyberpunk.
