Hello, other members of the Guild. I've been wanting to get into more of the site (like going to more Casual RPs, 1x1, Arena, etc) and I'm here at 1x1. I've only been in one 1x1 RP before, but my partner took a long break from RPG during this 1x1. So now, I've come and decided to make an interest check, primarily focused on Games. I'll list a few Fandoms I'm very intersted in, and you feel free to add or be intersted in any of them:

Portal- This would basically somehow involve the universe of (my favorite game series) Portal. This can be a sequel or a prequel to the second game. The prequel would most likely involve the man and Companion Cube from the Portal comic Lab Rat. Maybe how he and the Companion Cube survive the laboratory by running through and finding exits, and such. The sequel would most likely involve the ending to Portal 2, where Chell is told she's released, but that's not true, as the outside is just a large box in which she still is inside the lab and will continue testing, likely with new elements (like how the Goo was a new element, but something else similear to that).
Minecraft/Starbound- This is something I just want to suggest mostly because of the Roleplaying potential MC/Starbound actually have. I've seen Roleplays involving these games, and they were pretty amazing. Not much else to say, fairly obvious what the RP might be about. I would might do something Terrarria, but I also have not played that.
Super Smash Bros- This would be about where we could do a 1x1 brawl with any character from the Nintendo franchise. Pretty obvious, just ya know, a fight. I have little experience with actually RPing fights, but I'm learning. 
Pokemon: Henko- Multiple things could happen with this. This would be based in a new region of Pokemon, Henko. There would be new Pokemon (made by us) and new people with a storyline and plot. Here're the different ways it could be 1x1'd, Pokemon Team x Trainer, Main Pokemon x Trainer/rest of the pokemon team, and Trainer/Pokemon Team x Trainer/Pokemon Team. More details can be provided about all of these if needed. The Trainer/Team x Trainer/Team could be romantic, but I'm pretty inexperienced about romance RPs. If you do want it to be Trainer x Trainer romance, it doesn;t matter to me if it's MxF, FxF, or MxM, your choice. 
AnyFpsEver- Preferably one with aliens. You name it CoD, Battlefield, Halo, and FPS and we can do it. It would be more story based than the actual games, but it would involve something along the lines of: a team of people in whatever military they're in, focusing on two different characters in this team controlled by each of us. The team either would end up either leaving us behind (thinking we're dead, or soemthing like that) or getting killed, leaving the two alone to fend for themselves. Most likely not romantic, but somehow it could be. In this, I would prefer MxF for romance (that is, if there is any at all).
Mario- Somehow, I think a 1x1 with the Mario series could be possible. Maybe if it was more story-based, with most likely Mario x Luigi having to team up because Bowser has gathered his army yet again and kidnapped both Princess Peach and Princess Daisy, something that angers both Mario and Luigi.

These are about it for now, feel free to add ideas and suggestions, and tell me if you're interested in any of them.
