I wasnt much of a sonic fan so no tbh. I heard Frontiers was pretty good but 3D sonic has always had issues.
Regarding DLC and difficulty, I do think this is partly the fault of consumers. DLC is always harder than the base game since the devs assume that players who play the DLC have at least beaten the base game and want more and adjust the difficulty accordingly. DLC is always a step up, the point where the enemies can be incredibly difficult compared to the base game which becomes jarring to be honest. I remember playing Ghostwire and getting absolutely owned by this umbrella yokai and later found out it was added into the game later as "free DLC."
Yeah, complaints for more difficulty tend to be bad imo because difficulty is only good if the base game mechanics are sound imo. If the base mechanics have issues, higher difficulty just leads to more frustration (although arguably higher difficulty is needed to really explore those mechanics). I remember the hype for Kingdom Hearts 3 critical mode being "difficult" and honestly not being that good because the base game still had issues.
(post ended up being longer than expected, but it shows the frustration, mainly of that final boss in the dlc)
I've been a Sonic fan since the first game. Sonic did and played better as 2D games, mostly. They still messed up Sonic 4.
I liked Adventure the best for 3D games.
If you google the difficulty for Frontiers dlc, you can read where a lot of people talk about this. Some is pretty funny with how a lot of people were quite frustrated over it. More so than any other dlc I've ever played.
Another ting about the whole game and dlc, was there was little direction on a lot of stuff, like boss fights.
The worst was the dlc final boss. It was a cool design and all, but basically, this planet like creature, known as, The End, is coming down to destroy Sonics planet. You have these giant Titan machines you've fought through out the game as bosses. You have to be Super Sonic to even hurt them.
After you defeat this last Titan, then The End uses this pink cord like thing, basically an umbilical cord, and then controls it.
Heres where it gets tricky. Now as Super Sonic, you fly in, dodging all this stuff, and it automatically targets the head. The game always had auto target. Except for this boss, after you do any type of damage, it instantly heals. No matter what you do, it heals.
So, off to google I ran....and found out, every single person had to do the same.
Behind its head is where that pink cord connects, on its neck. The game never even tells you, with its auto lock on, that you can change targets. I found SO many topics of people asking how. On PlayStation its R1. Like, really???
But, its so wacky, it might change targets, it might not, it might switch back to the head target on its own. Very frustrating.
So after only a little damage, that pink cord breaks off. Great, now you can actually damage the head without health coming back. I get it down to 0 health...and....nothing. Not sure what to do. Next thing I know, it goes to a little cinema of The End reconnecting the pink cord....and its life starts filling again. It takes maybe 15 seconds before its life is back to 100% fill. I break the cord off, attack the head and bring it to 0 heath. Cord reconnects.... this happens like 20 times in a row. I absolutely could not figure out what to do.
Everyone on line says to use a cyloop with Sonic. I'm not sure what that was, but was thinking it was this attack where he spins around. That ended up not working.
I'm watching video after video, and FINALLY found out, after breaking off this pink cord and draining its life and getting the combo meter maxed, you have to hold triangle. There is also another target with no life on the back of its neck, past the part where the cord connects. Even with no life, once the head it at 0 life, you then combo that and hit triangle. (people kept saying you had to attack the sword. I'm like, what sword???)
So now, with both targets having hit triangle on, the cyloop attack, now the sword comes out. Attack that, bring up the meter, and prepare to hit triangle....and oh man....we took to long, the pink cord just reconnected and now we have to start all over.
I was stuck on this fight for like 2 hours until I found out what to do. Thanks Sega for not explaining ANYTHING AT ALL.
