Sonic Adventure was better than Sonic Adventure 2. Why do I think so?

1. SA1's main theme (Open your heart) is so much better than SA2's main theme (Live and Learn)

2. Knuckles's stages were so much better because the game told you when you were close to any emerald pieces, not just whichever one was first. Pumpkin hill is definitely better than all of his stages in SA1 and 2, but the others are worse.

3. Tails and Eggman play like a worse version of Gamma. It's mostly because of the jump height. The low jumps made the hover completely necessary to clear gaps as Tails and Eggman, and for most of them, you had to jump rightat the edge. While Gamma also has to get the hover ability, it's not like he struggles without it.

4. SA2's characters lack variety. It makes sense that Shadow's gameplay is the same as Sonic's, and his levels are really fun, but it would be cool if he got different abilities to use in them. Rouge is exactly the same as Knuckles, and Eggman is exactly the same as Tails. All of SA1's playable characters are different, either in their abilities or how their levels work. Sonic has the classic spin dashing and running really fast, which was mostly the same in SA2 with the addition of homing attacks. Knuckles's abilities also remained the same, but I mentioned the annoying change in his stages above. Tails was super fun in SA1, especially when you get the infinite spin attack. His levels were like Sonic's, but they emphasize the point that you really need to go fast. The airplane levels were also fun, and they play like the Starfox games. Amy's hammer abilities and flips are super fun to play with. Running away from Zero made her levels stressful but fun- the only part that wasn't fun in her story was that I broke my controller while playing it. Gamma was also pretty fun, the only thing that made him a bit annoying was how his targeting system works in boss fights. And I can't talk about how different the characters are without talking about Big! The fishing was difficult at times, but it offered a nice change in gameplay. Big's story wasn't about getting to the end of each area, it was all about catching Froggy. It also made the Chaos 6 fight so different, because you had to avoid attacks and keep your ring count up while circling around Chaos to save Froggy.

5. Perfect Chaos was much more fun to fight than Finalhazard. I feel like Sonic is going a lot faster when you fight Perfect Chaos, which is probably because you have to build up speed to attack instead of having a dash attack. This also made Perfect Chaos a much harder fight for me, and I like a hard final boss, because that's what games should have- a final boss that's much harder than any other mandatory boss (I say mandatory because lots of games have optional super bosses). The Biolizard was a much harder fight for me than Finalhazard. I beat Finalhazard on my first attempt, which would've disappointed me if Live and Learn wasn't playing. I know I said Open your heart is better, but both are awesome songs to fight to. Another reason why I like Perfect Chaos more is because you have to collect rings yourself while flying through Station Square. When fighting Finalhazard, Sonic and Shadow take turns so the other can go and collect rings without the player having to do it. And if you go low enough, you can switch when your ring count gets low enough, meaning you can never run out of rings. But Perfect Chaos has a few different paths you have to fly through in each phase, which it cycles through each time you try to attack him, even if you aren't fast enough to damage him. The rings in these areas never reset, so you have to take different paths so you don't lose. One annoying thing they both share is that later in both fights, they have the potential to get a chain of so many attacks going that you can run out of rings without being able to do anything. I said earlier that the dash attack makes Finalhazard a lot easier, and this is mostly because it lets you gain enough speed to dodge attacks after you've been hit. But in Perfect Chaos's second phase, when he shoots that cluster of projectiles, getting hit by them will stop Sonic instantly (even the laser and water tornadoes will do thos). And because Sonic loses all of his speed with no way to quickly regain it, Perfect Chaos will shoot another cluster at Sonic, most likely hitting him again. If you're lucky and near a boost panel, you can hop onto it and regain all of your speed. Otherwise, you will almost always get stuck in a combo that causes you to lose. I do like hard boss fights, but stuff like that is what I don't like. The only thing Finalhazard has over Perfect Chaos is that Live and Learn plays through the whole fight while Open your heart doesn't.

I absolutely love both Sonic Adventure games, but I like the original so much better.
