The secrecy must be unrewarding, but it's the best defense against lawsuit-happy IP holders. When word of mouth begins to spread, you better be ready to release and run because it's only a matter of time before Nintendo's lawyers start gunning for you.
SteamWorld Heist II (Steam, PS4/5, Xbox One/Series, Switch)
Like its predecessor, it's basically "2D XCOM with skill shots instead of randomness". Highly recommended, perfect for gaming on the go with a Steam Deck or Nintendo Switch.
He's well liked because he came from the trenches and has a good track record of knowing his shit. When compared with the likes of Kotick or Guillemot, it's a breath of fresh air (despite being such a low bar). However as one of the highest execs in the entire gaming industry, this is the kind of stuff he does all year long.
Plus you know, his public-facing image is well curated and people like it.
The Crusader series (No Remorse, No Regret) could have been built upon, with its famously cheesy live-action cutscenes.
The Quarantine series disappeared after its second installment, Road Warrior. Come to think of it, most mainstream vehicular combat games went away, like the Interstate series.
The Discworld adventure games (1, 2, Noir) were famously convoluted, but they did a pretty good job of adapting Pratchett's world into video games.
Finally I would have liked to play the initially planned sequels to Advent Rising. I have (probably rose-tinted) fond memories of that game, but hey, you asked.
The Epic Games Launcher is so far behind on features compared to Steam it's not even funny. Epic chose not to try and compete with Steam on that front and to try and force users onto the platform with exclusivity deals and sweeten the deal with free games.
The one user-centric killer feature Epic has in their stack IMHO is the built-in multiplayer crossplay. Except it's not even exclusive to their store ironically (you do need an Epic account for it though).
In the space hulk og board game and most video game adaptations, Space Marines die very quickly to genestealers and such.
Even in the first SM game, the resilience came from doing melee executions (akin to glory kills from doom) which triggered health regen. And you were not even immune to damage during the animation !
Guild Wars 2 has been my theme park MMORPG of choice on and off for the last 12 years, with >2500h. I have also spent ~1000h on Elite Dangerous.
