So after picking up Ar Nosurge I got sentimental about the Ar Tonelico series and I grabbed my AT3 disc for a little nostalgia. I popped it in and played for an hour or so, loading my clear data and starting from the beginning.
Wow. I was floored.
Now this is just my subjective opinion here, but after about 30 hours in, I like Ar Tonelico Qoga much more than Nosurge.
Ar Tonelico Qoga has:
-better music, hands down. Seriously, pop AT3 back in for a few minutes.
-better characters, lead character especially. Delta is such a fucking wad.
-better character animation (just check the idle animations in the AT3 gallery)
-better frame rate
-better art (backgrounds, city transitions, 2d + 3d mix, picture unlocks)
-better conversations
-better bosses (except that one we shall not name)
-better anime interstitials (higher quality of AT3 is instantly apparent)
-better story setup/reveals
-deeper, more rewarding cosmospheres (so far)
-easier menus and upgrades
-better (jp) voice acting
to name a few...
Now, on the subject of the battle system. I quite like Ar Nosurge's approach. It's satisfying and can be quite strategic on higher difficulties. That said, I miss the connection to the Reyvateil that Qoga has. Running back to her to heal, blasting enemies off of her, harmonizing your attacks. It was more engaging to me.
Here's my take. Qoga was the last in the AT series. It was a labor of love and a love letter to all the AT fans. They took the fanservice over the top, sure - but the rest of the game exudes quality in almost all aspects.
Compared to AT3 (and most definitely AT1 + 2), Nosurge seems like a budget title.
I have been a huge fan of AT for many years. I have been looking forward to this game for a long time. I may change my tune after 60 hours with Nosurge, but as first impressions go, this game is the worst in the (loosely connected, thematically similar) series.
