Im always going to buy the pokemon games but they are decreasing in value somewhat.
The game is like all other pokemon games, you get a starting pokemon in your initial town, make a rivial, and then go out around the continent and capture pokemon; get badges, and then beat the elite four. WELL there are a few complaints that i have with this one. First, this game has the largest pokedex (total number of pokemon) but why is it that every single freaking route i go to has the same 3 pokemon. then all the good pokemon are around three areas. Also they added the new night system back but you can barely find any new pokemon except for hoothoot. Then when you get your national pokedex you can barely find any of those pokemon. Fortunately they've added a couple of new things like the ability to transfer your old pokemon from R/S/E/FR/LG to D/P but then that kinda defeats looking for and catching all the other pokemon. I did this and now that i have almost every single pokemon my exploration as dwindled down to just staying in the pal park area and importing pokemon. Though if you do use pal-park to just obtain the pokemon that you cant get in D/P (legendaries and starters from past games), and some pokemon that you really used. Then you might be able to expand the games time by two or three times. I've played for about 70 hours, which isnt actually that much there is still tons of stuff to do, but i just got bored of it. Im not sure why, in ruby i played for 250 hours and never got bored. The story itself will probably last you 20-30 hours.
The review so far has been a little harsh but the game is still great, The new 2.5D graphics look very good and the GBA pokemon games look ugly in comparison, they do have some unique locations, like a flowery feild, which is also a town, and a windmill powerplant. They've also put the daytime and night time system back in and their are tons of side quests and little things you can do, depending on the time and the date!
The sound, is kinda dull it may get on some peoples nerves, its rehashed from the previous pokemon games though i think there maybe a couple of new tracks.
There is alot of replayability, mostly because there is so much to do, but also because this is the first pokemon game with WIFI! so that means you can battle and trade all around the world. This is a nice feature if you want to test your skills or if you need a pokemon that none of your friends have.
All in all the main pokemon series is still going strong. Though its gotten little weaker then previous titles; I highly reccomend the title, which will last you a very very long time. And the kiddies eat this stuff up, this is all they talked about at summer camp(so if youre a parent pick this up for youre kid espcially if they like pokemon).
