Pros: Excellent graphics, tight controls, lobby menu is nice, lots of stuff to unlock
Cons: Same problems with original game, tricks are too simple
Snowboard Kids 2 makes changes to the Snowboard Kids game for better and worse- but mostly better as it drastically improves on the game's designs and makes for a better game overall.
This is still an identical game at its core to the original: you are on a snowbard, you race down a hill, picking up powerups and doing simple tricks with the hopes of speeding up and getting ahead of your opponents. The game offers you six different boarders but it seems their stats are removed, which is odd. If they aren't the game doesn't tell you what the stats are (I later found that the stats are hidden away in the 'internet' selection mode in basic descriptions of the characters, which is odd) The boards still have stats, so it's probably a decision done to simplify the gameplay, which is good.
Once you have a boarder, there's only one real mode to choose from: the story mode. While it's just one mode, it has a lot more in it than the typical game from this era. You've got the small lobby where you can do a few different things: select from minigames, race the main races, choose a board, paint it. There's also an "internet" which is kind of funny. It's just got a lot of information on it about what you've unlocked so far.
In essence the game is just about the racest, but the extra modes are nice too. You race against four other boarders on a downhill slope and then at the end take a chairlift up to do another lap until the goal is available. The racing is fun. The cartoony style makes it more like a party game than a sports game and there are powerups littered all over to add elements of surprise. The game removed the ice conditions for the most part so it's much easier to control the board, which makes this game superior to the other one in the controls department. The music is good and the graphics are exceptionally well done, bright, colorful, cheery and bursting with character. The whole interface is also really well put together and immersive.
I think the only thing you could really fault this game on is that it's cheap like Mario Kart, leading to a lot of ridiculous situations where you lose for no real reason. Also, the exit at the end of the chairlift is tiny, if you forget to head to the right side at the end of the course, you crash into the wall and are basically screwed.
The game is well done in every other regard. The boards control great, you can jump, and hitting the ice really feels good and responsive as you regain control after the jump. There are two types of powerups you can pick up. One is an attack, the other some kind of powerup, typically speed boost. These do things like slam pans down on your enemies, send hands to knock them over, encase them in ice, and more. You can also bust tricks which are very simple and limited but fine. You have only two that I discovered, a flip and a spin. The game could've added more tricks, my memory is foggy but the excellent game SSX improved on this stuff a lot. The tricks may or may not speed you up, I think they do but it's hard to tell since you speed up when you land a jump anyway. The tricks are important in a trick mode where you rack up points, but this mode is pretty basic all the same. There's also a target shooting mode like in the last game. I would've liked to have seen more modes. The main unlockables are stages and characters. You also unlock hints, music and other stuff on the internet section of the lobby.
Overall this game is very well done and superior to the original, though both are very good snowboarding games and I recommend giving both a try if you like these sorts of games.
