Note: I haven't played multiplayer, so I can't comment on that aspect of the game.Lock's Quest is one of those games that doesn't look like it's going to be particularly amazing, but when you begin playing it's hard to put down. Everything from the story, graphics, gameplay, and music helps draw you in to this game.Plot: You (Lock) start off in a small, peaceful village living with your grandfather and your sister Emi. After your town is attacked by robot-like enemies known as Clockworks you are forced to flee for your life. Unfortunatley, Emi is lost in the escape. You learn that Archineers are defending the kingdom against the forces of Lord Agony who is using the Clockwork army as his loyal minions. You train as an Archineer to serve the kingdom, and your adventure begins. There are a few twists that keep things interesting, and the dialogue is actually pretty good.Graphics: Visually speaking, Lock's Quest is appealing to the eyes. The colors are cartoon-esque which gives the game a light-hearted feel, but there's more than enough detail to the game world to keep things looking crisp.Music: Lock's Quest has music to match the graphic style. Nothing is too serious, so everything remains light-hearted and fun. Still, the music tenses up when the mood requires it. Nothing is amazing here, but it's appropriate for the setting and style of the game.Gameplay: The Key to this "Lock" is the Stylus. You use it for pretty much every command in this game, and it works flawlessly. As far as game flow, you are given an objective(s) (protect certain targets, capture certain targets), and then you are granted a period of time to set up your defenses. Source (earned primarily through killing enemies) is the material used to build your fortifications, with each structure requiring a certain amount to build. Turrets are built for firing at enemies, walls are cheaper to build and add defense bonuses to your turrets, traps cause side effects to enemies that set them off, and helpers offer special benefits to your turrets/walls. You can place any combination of these structures on the field as long as you have enough source. Most maps have several rounds to play through, so you need to keep your structures alive as long as possible so that you don't waste source (between rounds you can spend source to repair damaged structures). Also, traps only last for the round that you build them in (fortunately, they're cheap). You unlock structures as you progress through the game, and you are able to build with sturdier material (wood, stone, then metal). While you're fortifications are doing the bulk of your work for you, Lock can fight enemies as well with a variety of attacks that are triggered with different uses of the stylus (making circles in a given direction to poison enemies, tapping numbers in ascending order for extra damage, etc.) He also has super powers building up as you attack enemies that can effect the entire board. Fortunately, Lock can also repair structures mid-battle at the expense of source, so if your walls are crumbling before your eyes there is still hope!Overall, Lock's Quest is a great game for RTS and Tower Defense fans. You can make different fortifications each time you play, so there's replay value after you've beaten the single-player campaign. Although I haven't played the multiplayer yet, I'm sure it will also add plenty of extra play to an already amazing game.Good game, interesting take on tower defense. My one issue is that when the hordes are at the gates the stylus control doesn't hold up. You're trying to repair a tower but you are fighting a dude or you're doing a special move but it fails because the touch screen isn't up for the task. Now I'm not only blaming the DS but I think between 30-40% of the failures were on the system while the other 70-60% were on me.Father: I enjoy playing this game too. Good use of the DS's platform. It changes up the different missions but reuses the strategy of building. It's not just another battle game of running around shooting things. You have to figure out how to apply the given building blocks, traps and helpers. Worth buying. It challenges my son in a constructive way. We'll be looking forward to more games this company puts out.Son: This game is really cool. But it is hard for me to learn about it. I was looking forward to playing this game after seeing the commercial.Got this for my 13 year old step-daughter, she loves it. She gets bored with games that are too easy and easily frustrated with games she can't figure out, so it is hard to find in between! This was perfect. Great game and very good value for the price!I bought this for my 8 yr old son, who loves the Professor Layton games. It is similar in that there are challenges to solve, but it doesn't have quite the same appeal. A good buy for your DS money, but not the best in class.Package arrived all safe and sound!!!!!! Thanks for the great service!!! Back to viewing the all mega great total eclipse!!!Poppy in GeorgiaYoung players and those who enjoy dungeon-building have the best chance of liking this game, but I found it a bit short and unsatisfying. Watch gameplay videos to see if its style is for you.I had a lot of fun playing this game, there were some little annoying gameplay elements that ALMOST made me want to yell, but overall, this game deserves a chance for those who love strategy games.
