I aslo have the four; Mario Kart, Metroid prime hunters, Tetris and Animal Crossing.
Animal crossing is great for relaxing, and some easy gaming; i generally have spurts where im on it ALL the time, then wont pick it up at all for a month...
I havt been on MK for ages, though i really should...I used to play it a lot.
Metroid is for the more competitive gamer. And i find you are either really good or really bad; i guess it depends on how you get used to the odd control system.
Tetris is what i play mostly at the moment, mainly because it's the newest; TIP: If you're on single player classic and have played for over 30 mins. TAKE A BREAK! I played for an hour and a half straight to get my 5 mil score, to find that i couldnt move my arms higher than my neck...ouch.
P.S I agree with the MK cheating. You can't really 'cheat' on MP:H though you get a few who disconnect. However on tetris, you get the win if your opponent disconnects. Thats another reason why im playing it so much at the moment.
i say dissconnects should vary, if you at the time had the higher overall score, then you get the win, if you did, or both had a tie, you dont get a wiin (<LOL im not fixing that it was an accident swear to god,) nor a loss.
I love Nintendo's online service. For the price we pay for it, it's a very good service in my opinion. Play "anyone" in the world who is online with there DS. The only problem I see with it (which I think they are now fixing) is that once you play someone you like playing with, there's no way to add them. I here MP:H has a sorta voice chat lobby, but I'm not sure. I only played it 3 times online and got my butt handed to me.
same here i have AC:ww, tetris, mkds and mph.... i like tetris because there isnt any way to cheat..... i like mkds when people dont cheat and just playt, im not that good at mph, so its hard to play online when im dying all the tiome haha.... and ac:ww.... it was fun for a while, and i agree i find myself playing it all the time at once and then not playing it for like a month at a time... haha... fun fun i excpect to get starfox to play it.... OH i also have lost but im stuck on a part and dont know waht to do so i gave up on that game it was cool and boring at the same time...... VERY neat/creative i dea for casting spells by drawing them tho
