TrueSteamAchievements has this (in Easy Achievements). Source: 6 months ago

It does happen perfected games get new achievements added. Maybe that's what happened to your missing game? It's a real drag to make a separate list to compare Steam's list to, but maybe it's worthwhile signing up for something like True Steam Achievements if it's important to you. Source: over 1 year ago

OK looks like they've been picked up by truesteamachievements.com and some people have them unlocked. Source: over 1 year ago

Whether 100%'ing a specific game is worth it or not depends entirely on your preferences. I wouldn't put too much focus on achievements unless it brings you joy. I can't give you recommendations since I don't know your tastes. I'd simply pick a game you like. This website can help you track your progress, and it also has guides for most achievements.

I got the game from freegogpcgames.com. The shortcut you see there doesnt work at all and just opens file explorer. I succesfuly opened the game after the setup with that launch game button and it worked perfecty, but when I closed the game there wasnt an exe file to launch the game. Any help would be apreciated.
