Yeah, I think DS games are good and everything, but for a deep game like TES the PSP is the obvious choice - more power, more data storage, better 3D graphics etc - you can even download content for some PSP games.
Oh Bruntie, the way you constantly attack the DS is just so adorable...
Now, let's see your points:
- More power: They've made it clear that they couldn't (or wouldn't want to try to) get a massive, open world, first-person RPG onto either platform - we're looking at some kind of dungeon crawler whether it's the PSP or the DS. In that kind of context, what use would "more power" be? Either of them has ample power for running around in narrow corridors, slashing the crap out of stuff until it dies.
- More data storage: Yeah, the PSP's UMDs definitely hold more data. You make a game on the PSP and you can count on people expecting far better models, far higher-resolution textures, MP3-quality music and spectacular overall presentation. Maybe even voice acting. The DS is neither capable of nor focused on that level of presentation, meaning that its various assets would take up far, far less space. As to whether or not the difference in space is enough to make a DS TES game more reasonable... well, if it's going to be a dungeon crawl, I don't know how big you can reasonably expect it to be.
- Better 3D graphics: Look at the size of the screens. No one's going to care if the DS's graphics are low-quality, because the small size makes them far easier to stomach. Also, you've vastly exaggerated the weakness of the DS in that area (I'm guessing you haven't played Dementium or Ninja Gaiden: DS). And, as always, we'll have to invoke the "graphics don't matter" stuff. Really, they're the least important part here.
- Downloadable content: Wouldn't be in a PSP TES game. Downloadable content isn't that common to begin with, and Bethesda certainly isn't likely to start providing FREE content for a spin-off that, in all likelihood, would be little more than a cheap cash-in game.
Now, I think I could probably come up with some more convincing reasons why it
should be on DS.
- It's a natural fit: The TES series has traditionally been controlled with a mouse and keyboard, and while the DS doesn't have an entire keyboard at its disposal, it does have the next best thing to a mouse: a stylus. In fact, the DS's stylus is perfectly suited for the style of combat in the older TES titles, where the swing of your weapon was determined by the motion you moved your mouse with. It's also easily tops for menu navigation, inventory and character screen navigation and manipulation, and interaction with environments and other things, all of which feature fairly prominently in the TES series.
- It would be cheaper to develop and likely more successful: The DS's development costs are extremely low, by far the lowest of any current gaming machine. This means that the investment in the system that Bethesda would have to make would be extremely small. In addition, the platform's proven to be a haven for older styles of games, things like TBSs, graphical adventures, and - you guessed it - RPGs. Add to that the size of the DS's user base (over 70 million, which is more than double the PSP's 34 million or so), and they've got a recipe for success, something that could lead to more portable TES titles and more interest from Bethesda in expanding the Travels franchise (not to mention that it's just good business sense on their part).
That's it, actually. I'd wanted to come up with three reasons, but I can't think of a third. After all, if the fact that it'd be considerably more playable and (if done right) probably considerably more fun, or that it'd be more likely to lead to more portable TES games across all handheld platforms, isn't enough to convince you, then I'm not sure what would be.
