OK, I'll write up a proper dissenting view of the praise this game is getting in this thread, because having played it extensively I have to say the following:
The Dragon Quest series has always had a very set way of doing things. It's an old fashioned Anime-based RPG and is proud of the fac it does things the way it does. Having played the previous DQ on the DS, I was both impressed and left underwhelmed by the title but having read the hype regarding DQIX up to its release in Europe, I was actually really excited about the title in a way I haven't been about an RPG since FFVIII following the stunner that was FFVII on the PS.
So DQIX is the first title I have bought on release day for any gaming system in about 10 years. The initial presentation upon boot-up is encouraging, with an action packed cut scene. Square Enix have said they wish to focus on combat with this game and it certainly sets up for that.
The character customisation is, without a doubt, the most versatile ever seen in an RPG. This ranges from the initial character design to (a few hours into the game) the choice of professions. You can choose how your hero and your other party members (three in total, but you can have a reserve of many) look and fight. However, this comes at a massive cost - the only character that "exists" in the main plot is the hero. It's hard to explain, but your three other party members pretty much don't exist. They're completely silent and completely ignored by the plot.
And it's the single biggest blow to this title - the emphasis on multiplayer has killed what could have been a fantastic game. Naturally, Square Enix had no choice but to have generic party members when the link game involves characters from other universes, but it was a poor choice.
Why? Well, namely the link system design. There isn't a WiFi global multiplayer option here. Instead, DQIX resorts to the age old local multiplayer option, relying on the hope that you have a close friend who plays DQIX extensively. Unfortunately, most DQIX players in Europe will be few and far between (and probably in the USA). The system probably works in Japan as the DQIX hype has passed into popular culture and nearly every kid aged 10 and upwards will have a copy. Not so in the West.
The potential of the title to be a WiFi success is here though. The game is beautifully rendered and the gameplay is innovative - the combat system allowing you to pick and choose whether you encounter monsters or not in the biggest breath of fresh air to the genre since Crono Trigger. Allowing a Pokemon-esque Global Trade Station of invites to eachothers world would have made this title a must have, but perhaps that is something for DQ10 to consider.
Setting aside the multiplayer aspect, what of the solo storyline? Well, mediocre to be fair. Dragon Quest has never been on a par with the Final Fantasy or Suikoden masterpieces when it comes to storytelling, but in this instance it's particularly disappointing. There's very few personable characters (with the possible exception of Stella and "Fatguts" providing comic relief) resulting in a generic gaming experience of play-by-numbers for the first 30-ish hours of the game.
It's not a difficult game either. In fact, the most trouble you'll have is interpreting the outlandish names of the spells ("Zing" apparently means "resurrect") or navigating the absolutely woeful menu system, or figuring out the map (which isn't interactive, remaining static in the top screen.)
The game threatens to come to life "post-game", but sadly it resorts to filler - "fetch 'em" quests and grinding is abound, filled with monster designs that are repeated adnauseum (a teeny sanguini is one of the first mobs you'll encounter - sadly, a purple version named genie sanguini is also one of the last you'll encounter...).
There's a difference between "hundreds of hours of gameplay" and "hundreds of hours of repetitive manual labour". DQIX too often falls into the second category. Whilst the RPG lovers inside of us will love the DQVC selling us rare items over WiFi, or the grind for your new alchemised weapon, there's not enough to compel you to switch the DS back on for another Celestrian adventure.
And therein lies DQIX's biggest problem - there's no "pull" for the player, especially newcomers to the game. DQ is stuck between wanting to appease the fans of the series and pull in fresh blood - it ends up doing neither.
If you're looking for a truly massive and enthralling RPG experience on the Nintendo DS, you'd be wise to consider Suikoden Tierkreis (a little known yet fantastic RPG experience) or pick up Crono Trigger for another blast.
6/10.
