Thanks to everyone who answered to my rather newbie questions. I just could never convince myself to play this on a screen like 3DS has, and I didn't own the Sony handhelds so yeah. This game looks really fun, and what I've heard about the gameplay loop sounds convincing enough to give the game a solid try at the very least. Here's hoping they'll have a demo, an open beta or something - RPGs for me are hit and miss, if I don't enjoy the core of the battles and such it likely won't click, but if I love the battles I can gladly get even through hours and hours of gring no problem. Looking forward to this.
I can't remember the last MH game that didn't get a demo, so you're probably gonna be fine on that front. Even Stories got a great demo. Previous demos were pretty straightforward, drop you into a hunt with prefab armor/weapons/skills with minimal tutorialization. I'd imagine with World they will probably ease players in a bit more since they are trying to target new players.
And yeah, as was said already, MH has the fans it does because the combat is fun. But *nothing* plays like MH and it has a learning curve. Back in Freedom 2 I myself was turned off by the game for a long time because I stubbornly stuck with Longswords. Once I branched out and tried new weapons I 'got' the game. I know 'it gets good after 20 hours' is a meme at this point but Tri was that kind of game...it does seem that they are focusing hard on having World explain mechanics better. Regardless I know from experience that at least some new players are going to bounce off, but sounds like you'll be fine.
Hopefully there is a pre-release demo coming. Even better, they could include the training/practice area they've been showing at TGS. It would be extremely helpful even for veterans to come to grips with the new additions to movesets. I plan on picking up Charge Blade for this one so I've got some learning to do myself.
edit: got curious and looked up demo release dates for previous MH games. Seems pretty consistent that they come out about a month before release.
