as someone who doesn't have a good way to play RH DS and wasn't sure they had interest in playing the original(I do maybe kinda but didn't when I played this last summer), I loved this. I do think it's a shame the real sequel games of Fillbots and Shoot-'em-Up 2 are absent. also I wish it had more DS content(wish Munchy Monk 2 was in!!!!!!!) and extra games being locked behind getting perfects is annoying to me because of the limit of tries and then the subsequent effort of getting another chance at perfect... thankfully most of them are just from Fever, which I've also played, but stilllllll. but I really really enjoyed my time with this and had a ton of fun. the polish in graphics for all of the older games is really nice too, imo. that said, there's not enough new for series enthusiasts that played all 3 other games. otherwise, this is 100% worth your time. so much fun. also for all the fuss about Lockstep's difficulty, I didn't find it that bad. no way I'll ever get Superb on it tho lol
