So I got Alpha Sapphire a few days ago and I actually completed this pretty quickly lol. Anyways, this was a really cool game, and many of the things I saw from the original Ruby and Sapphire were pretty much the same as they were then, which I liked about ORAS. The soundtrack from ORAS was also absolutely astounding, and I just love the soundtrack, moreso than any Pokemon game in the series. Team Aqua and Team Magma are definitely more interesting, especially Archie and Maxie, as they have some more personality to them in these games. Granite Cave was definitely quite different, however, and Mauville City was surprising-it's almost like a miniature Lumiose City!! (but at least Mauville isn't that big and it's much simpler). Wally and Brendan/May are also much more interesting in ORAS imo. Aqua Admin Matt was weird though, he was like "Archie is my bro!! I live to serve my bro Archie!!" (someone tell me what Courtney is like in OR? I'm also kinda curious about Tabitha). Primal Kyogre was a huge pain in the butt because its Origin Pulse hits hard...like really hard. Luckily I managed to weaken and paralyze it with repeated Discharges and caught it in one Ultra Ball after a few resets. The Delta Episode was also really interesting...Zinnia was a really weird character but I found her to be a bit rude in terms of breaking in and snatching Key Stones from Brendan/May, Wally, Matt/Courtney, and Archie/Maxie, as well as crushing the dimensional shifter. I had a ridiculously underleveled team against Rayquaza and Deoxys though...with my Pokemon around Level 50 lol. Mega Rayquaza is definitely really cool though (too bad it's so ridiculously broken that we had to redefine Ubers and make a metagame called Anything Goes...lol). The Delta Episode was pretty interesting in general...and perhaps with the ending that's how Wallace becomes the Champion of the League (Emerald canon)?. But yeah these games are frankly really good and are excellent remakes of two great games, I think Game Freak did an excellent job with these two games and I think these are the best Pokemon games I have played yet beyond Ruby and Sapphire themselves...lol. If only we could rematch Gym Leaders and have a Battle Frontier lol.
Yeah here's a dump of my thoughts on ORAS...after playing through it.
