SA2 was a great game. Y'all be hatin'.
Here are the reasons that some of us may feel that Sonic Adventure 2 was shit:
-Its a glitchy mess, with falling-through-walls, homing-attacks-to-nowhere, framerate concerns, regular no-clipping, non-findable emeralds, instant deaths from minute water, boosts to oblivion, unresponsive controls and repeating juttery voiceovers.
-It has a completely purile script and horrendous voice acting. Its story takes the dignified simplicity of the classic Sonic games, and junks it in favour of unskippable drek cutscenes telling a nonsense story that Takashi Iizuka has shat out.
-Only a third of the game actually uses (tremendously shoddy) Sonic mechanics. The rest is dominated by repetitive clumsy shooting sections, and a purgatorial and faulty emerald hunting mini game that was designed by an incompetent.
-The least shit parts of the game advocate BOOST BOOST BOOST mechanics, devolving the franchise from multi-tier platformer to a superlinear homing-attack heavy "hold up and press boost" tour-de-force of mind-numbing boredom.
-The art style has aged badly. The music is (opinion) obnoxious and hugely annoying (/opinion). The levels are uninspired, hugely derivative of the first (and also crap) Sonic Adventure and completely uninteresting to plod through. The enemies are nothing more than floating homing platforms. The bosses are pathetically simple and bring nothing new to the table. Deaths are cheap and pointless.
-The characters are utterly, inanely annoying. The Rouge McBatTits is probably the prime example, but they are all irritants. The repeated soundbites of supposed hints are aggrivating.
-The whole thing builds to a tremendously unsatisfying conclusion, in which our annoying heroes must fight a space lizard for some reason, who was created by Doctor Robotnik's grandfather as revenge for the death of his daughter or something, before he was dragged away, chained, and executed by the United States government. The President is okay with his armed forces destroying an entire city killing thousands to try and hunt down Sonic, while Doctor Robotnik is allowed to do whatever the fuck he wants and consequently blows up the moon. Rogue McBatTits stalks Knuckles. Shadow, a pointless Poochie character, works with Sonic to defeat the Space Lizard and inexplicably dies. Robotnik, the once great 16 bit villain, stands with Tails. Tails says something like "we saved the world", and Robotnik responds with "and we did it by working together!", and at this point I feel the need to vomit.
So there you have it. Its okay for you to like the game, of course, your opinion is wonderful and so is mine. But for those that are hesitant to call this particular game a masterpiece, there is more to our perspective than mere "hatin". Thank you.
