For the past month or so I've been working on a 2D version of the game portal. It was a lot of fun at first, but I'm getting bored of it, I think the problem is I'm just not a huge fan of the game portal. I'll probably finish it up, but I'm starting to think of ideas for my next project. I definitely want to do a platformer, they are my favorite to play and I have the most experience in making them, but I'm not sure exactly what to do. I definitely want some sort of creative aspect that makes it different and enjoyable. I want something that is a bit challenging to make, but nothing that is too ambitious, I want to make sure I can finish it. I'm also leaning towards a medieval/fantasy theme.

Here are some games I really like that sort of show the style of game I'd be going for.

Let me know if you have any thoughts or ideas,
Thanks!

Realistically, you should come up with your own design. Most beginners/novices, and even some advanced developers go for a design (or influence), but the best games always come from the heart. Cheesy, I know, but sit and think about a design. It doesn't have to be completely original.

For example, imagine a game which was influenced by Mario, played like Elder Scrolls, combat like Street Fighter, and a story like Deadly Premonition. Sure, those are ideas from other games, but put together.... Is there even a game light it out there?

Bingo! New design :)
