I recently started a X/Y nuzelocke after this attempt I'm going to buy one of the two.  (and yes I will be playing OR in nuzelocke)

Why restrict yourself to Ruby and not Sapphire? lol

I'd go with OR, if you liked the original Ruby/Sapphire game, then you would love this to bits because it's the same with SO MUCH more. I'm still shocked by all the cool surprises that I'm getting.

Also if you get OR soon, you can benefit from getting the free mythical pokemon for that game as well.

zanderlex : Currently my only game is y so I have no experience with either I chose OR because I heard groudon was better than kyoger.

shadowlink42 : Better isn't really something that's used in Pokemon, it's mostly based on what type you want, do you prefer water or fire?

zanderlex :   personally I prefer fire anyways but I heard that groudon nullifies most of kyogers attacks

shadowlink42 : Birthright has a lot of replay value because of the difficulty settings yet this pokemon game falls short in my opinion since it is just like Y with new megas and no frontier.

shadowlink42 : Have you done any research beyond the main legendary Pokemon? There are other differences from version to version. For example, whether you get Latios or Latias (although you can get both in the same version with an Eon Ticket). There are also other Pokemon that cannot be found in the other version. Personally, I like Kyogre more than Groudon, but that's personal preference. Find the version that works best for you!

As for my recommendation, it's going to be the Pokemon game.

I would say Fire Emblem, but it's not really about me here. Seeing how the thread has gone and what you've been discussing, it would seem as if Pokémon would be the better choice. Regardless of how the poll turns out, decisions such as these should be made internally, not from external influences. Do your research, weigh your options carefully, and pick what you think will better suit your needs / wants. It's kind of hard to compare Fire Emblem and Pokémon, as they offer quite different experiences.

I highly recommend you play Omega Ruby, it's a pretty faithful remake of Ruby and has a ton of references to the game it's remade from. Only thing I find stupid in it is that there is no Battle Frontier which is kinda stupid to me.

Both are two completely different RPGs that deserve equal respect but I'm gonna have to go with Fire Emblem with this one. I only chose Fire Emblem because Pokemon Omega Ruby and Alpha Sapphire were remakes to Pokemon Ruby and Sapphire. You can't really go wrong with Fire Emblem either it is a very enjoyable series.

I'd personally pick Omega Ruby because it's one of the best remakes you'll find out there. Everything that people loved about gen 3 is present here plus it has a really good post story and contests make their first appearance since Pokemon Platinum.

These two games while good are completely different. So it's difficult to pick one over the other. Choosing one really comes down to a matter of preference when it comes to what you're looking for in an rpg.

If you're looking for turn-based type of RPG, get ORAS
If you're looking for a strategy/tactical type RPG then Fire Emblem is the way to go.

For the sake of picking one over the other, I'd personally choose Fire Emblem, but mainly because I hold a bias for the series as it's one of my favorite ones. Plus I'm not the biggest gen 3 fan around, even though ORAS was pretty good.

Personally I'd say Fire Emblem, but it really depends on which series do you like more. I grew tired of Pokemon ever since I finished playing Pokemon Yellow. I bought Pokemon X 'cause I heard it has lots of Gen I pokemons and they finally got their 3D (and animated) appearances in the game. At first it was fun but I got bored of it really fast (I don't know, it felt really bland to me). Now I refuse to get another pokemon game; I just can't play it anymore without cringing.

Fire Emblem on the other hand, I really like Awakening and the only reason stopping me from buying the newest entry is that I want to completely finish Awakening first before moving on.

Your choice highly depends on your taste though. The only thing we could do is to share our biases and opinions based on our experiences. Those experiences might not be of help specially if we don't have the same taste as yours in gaming.
