The only hitch is you must have consent anyway, like Arkanoid to Break Out.
That's true under a specific subset of circumstances that doesn't seem like it fits here.

I sat down with my notebook and came up with 3 games. I thought up 3 stories, each with (what I thought were) unique puzzles. On coming with a name for them, I checked the Interactive Fiction Database (to make sure I wasn't using a name already taken) and I stumbled across 3 games, each much like what I had envisioned (although better than my own) with fairly similar puzzles. How do I make a game if all of my ideas are already used?
There's nothing wrong with rehashing a plot or puzzle. Depending on the similarities, implementation and style might be enough to set you apart. I'd make the game you feel passionate about. I'm not so big on puzzles, so you might want to take this with a grain of salt, but there tend to be certain classic puzzle types. They get dressed up in different clothing, but a truly unique puzzle is pretty rare. It's certainly not necessary for a subset of your potential players.
On the other hand, if you really feel driven to write something unique, then you'll need to come up with more ideas, spin the old ones in a new way, or combine/strip down ideas until you've got something. That process is different for different people, and that's not one of my skills. Look into brainstorming techniques, or bounce ideas off a friend, or use Seventh Generation's random plot generator or whatever helps get you into a creative mood, and see what emerges. (I use Writing Down the Bones by Natalie Goldman to practice getting my brain moving and passing that internal editor. In itself, it doesn't help with plot, but it helps me get into the creative space and just *get started*.)
