I have Resident Evil wii, Mario Strikers Charged, Zelda, Tiger Woods 07, Madden 07 and 08, Wii Sports, Rayman Raving Rabbids, and wiiplay (cause of the free wiimote for cheaper than an actual wiimote.) and ive rented pretty much every game thats come out. Here are the Highlights.
My Favorite is defiantly Resident Evil, but im not sure thats a game to give your gf. Plus, its the same story as Resident Evil 4, but just changed controls for wii. Its not a bad thing since RE4 was FREAKING INCREDIBLE, but it loses a bit going about it for the second time around, although it does have the added PS2 bonus' that weren't there for gamecube version.
Mario Strikers was really fun.....for 10 minutes, then it got incredibly boring and repetitive, although the controls are easy to learn and it isn't complicated, making it a decent party game (if your party lasts 15 minutes). Was really disappointing because EVERYBODY heralded this game as the return of jesus in the form of a video game. and my only thought after playing it was "Meh, it was ok I guess" and the AI is Cheap instead of skilled in 1 player (ie. every shot that the computer takes WILL result in a goal no matter what in strikers cup)
Zelda is zelda.
Tiger Woods is surprisingly fun, and i'm a huge golf fan. the putting system is lacking in true form, and there is ways to get around the control scheme to cheat and hit it straight 400 yards every time, but if you use the controls LIKE YOU ARE SUPPOSED TO, then its really deep and fun since your shot control is based on both pitch and yaw of the wiimote just like a real golf swing. Think of this game being -almost- as fun as actually playing golf, as well as much cheaper and not as cold in the winter.
Madden 07 was awesome and the control scheme was amazing. When my buddies come over this is all they want to play. Its super smooth control and really fun.
That being said, Madden 08 is PURE SHIT AWFUL THE WORST GAME EVER MADE I WANT TO THROW THIS GAME INTO THE RIVER. the graphics are worse than sega genesis, the controls SUCK ASS, and you cant even make the throw motion anymore on passes because it wont get picked up that you did anything. I would only buy this game again if I was going to use it to break in half and stab a tiburon worker in the jugular with.
Wii Sports = Smoothest game. Best Party Game. Worst game to play while drunk, wearing socks, and playing on a wood floor.
Wii Play = best value, since its 19.99 and wiimotes are 39.99 or something, but the game is really awful.
I rented Paper Mario, but it wasn't that great. it looks way more exciting than it actually is. I honestly think that it got such good press because it had "mario" attatched to it. If this was called "Super Paper Fred" nobody would have wasted their time.
SSX blur was fun, but also another rental type game, but the fun did last up till I had to return it. I wouldn't pay 39.99 for it tho.
I haven't played Metroid yet, I plan on renting it before I buy tho since Ive hated metroid since its original incarnation.
Mario party 8 was pure ass stink in a box. (with pure gold min-games like "Row yourself down a river" and "Punch a statue" you have to wonder where they went wrong!)
Sonic was ok, better than the score critics gave it, but I wouldn't buy it unless you were looking to get the best game to look at while tripping.
Super Monkey Ball was ok, but I would just get the gamecube versions since this isn't any different and the gamecube versions are cheaper.
------------Dont read anything above this line-----------
-Editor's Girlfriend Pick- Rayman Raving Rabbids. This is the game my GF loves to play whenever she comes over because it screams cuteness (nothing cuter than bunnies with rabies) there are a ridiculous amount of games on it that once you unlock you can go back to at any time for party purposes (ranging from shooting rabid rabbits with plungers like an FPS and you can Co-op it, to Racing pigs across a beach a-la mario cart w/ pigs) her favorite is a Taiko Drum Master knock off game thats hard to explain, I think its a somewhat boring mini-game unless you get to the really hard levels, but she loves it on easy mode, so w/e. (I like the shooting plungers game).
So conclusion = My pick would be resident wiivil, but since you are buying for your gf I would go with Rayman!
Oh and on another note, i'm sure people will say "ZOMG GO ZELDA" but say goodbye to your wii for the next 2 months while she monopolizes it since its a 1 player game. But ya, its a good game if watching other people play is what you like doing.
P.P.S - That clip in Lostsoul's sig is from Wii Rayman. (Those are the raving rabbids)
Edit: This one
PPPS. I just remembered that MLB Power Pros is coming out. Im gonna try to rent that ASAP and ill tell you how it is...Looks great so far, but there arent any reviews on it...seems like none of the review companies care. Would be nice to have a decent Baseball game tho since "The BIGS" was terrible.
