The game is fun for a few hours but then you realize wow this game is one of the most repetitive games ever. Sure the are some different mini games but they all suck and to make monster parts you have to play the same boring mini game over and over again. But the battling is kinda fun, like when you blow off your opponents head with a shotgun.
Monster Lab is a unique sort of RPG in which you gather ingredients as loot from battles, use those ingredients to make parts (via Wii motion based minigames), and then assemble those parts into monsters. It's a refreshing change from the usual "leveling up" system, and is a very nice idea. Likewise, the combat system offers something unique. Each part has an element, its own hp, and 2 built-in moves that target specific parts on the enemy monster or even allow you to block, thereby damaging enemy parts. (It's a battle system a little bit reminiscent of the Front Mission games, but set up as a turn-based RPG.) The game has significant drawbacks, but it's definitely worth a rent.
-Interesting alchemy-based leveling system
-Combat system that's simple but offers a good bit of strategy
-Pretty fun visually to see your parts put together into a monster. Offers a bit of artistry, almost like Spore.
-Somewhat poor system of menus and displays. The information you need can be tedious and time-consuming (or even downright impossible) to access
-Too many loading screens and repetitive instruction screens. Sometimes you can spend more time loading and watching intros and info screens than you do actually doing things, especially when it comes to combat
-Story is painfully simple and pretty much nonexistent.
-Cutscenes have very poor sound quality and are not subtitled. I found it nearly impossible to hear any of the dialogue in the cutscenes
-A lot of things in the game get very repetitive. The game makers skimped way too much on variety. It was fun for the first couple of hours, but started to drag near the end.
-Some game objectives are vague or poorly explained. I had to consult a walkthrough a couple of times just to understand what I was supposed to be doing.
During my experience play Monster Lab i was throughly entertained. With over 100 million monster combinations you can create in surprisingly fun mini games, monster lab will keep you building and creating in a sea of endless fun. Monster lab can be very hard, but also very easy. Now i know people always compare games to Cod or battlefield 3, and i honestley do not think any games could be better then them. This is a very unique game, unlike any other i have other played. So stop comparing and give it a try, you will be surprised.
