launchpad cleaner or something like that should help you to delete them manually

You could manually remove entries from Launchpad while it's onscreen by holding down the Option key and clicking on the jiggling apps.

For steam games that won't work.
you can wipe out launch pads icons with the terminal command line:

sqlite3 ~/Library/Application\ Support/Dock/*.db "DELETE from apps; DELETE from groups WHERE title<>''; DELETE from items WHERE rowid>2;"; Killall Dock

All your icons will be gone - now just add the ones you want by dragging them onto the launchpad icon in the dock.

It does seem dumb that you can't just right click and dleete or drag to trash.
But then as much as I love OSX - there are many DUMB things.
While I love Mac and OSX - I hate apple as a company.

So as far as I can see it, here's the way to do it:
When you open the finder window, there's usually an applications tab on the side. You can click on that, but I didn't find my applications shortcuts in there. Not most of them anyway. I found them by clicking on my user folder, THEN on the applications folder in there. It's easy to assume that the two are the same, but they actually aren't. My user folder held all the unwanted shortcuts, and then I deleted them.

Excellent. However, macOS is trash for playing games on.

10 Years later and still valid thanks a bunch mate

For me, once moved to trash from ~/Applications you must still empty the trash. I tried moving all the steam .app's to a tmp folder so I could revert my changes but launchpad somehow knows I then had to run `killall Dock` to get it to realise they were finally eradicated (they still appeared as white "?"s, but a second kill cleaned it up thankfully)

This thread was quite old before the recent post, so we're locking it to prevent confusion.
