Some would argue that they've been taking advantage of LRG collectors for quite some time.... oh wait.
Pass on all three. The Gradius clone doesn't look bad, but it's a Gradius clone. Gradius Collection is fine enough for me honestly. I'm just not much of a shmup fan is all, so doesn't interest me enough to get it. When Senko no Ronde releases I'll get that though, and if they ever release Jamestown which apparently someone from LRG mentioned it as it's been rumored to get a release. The other two look like trash and even if I was interested in getting Fallen Legion, which I'm not, I'd get the Switch version which contains both stories.
