Congrats! Welcome to B8. We have a phobia of western games here. Fun fact: a game only needed 2 nominations to be considered, and only 8 games with 2 nominations were cut. Those games didn't get in because they couldn't get 2 nominations, which is pretty bad. While it doesn't reflect on the quality of the games, it does reflect on what B8 thinks of them. I can't control what B8 thinks, unfortunately.
Second, there is nothing wrong with any game you listed. A very large point of this contest is to see how niche games do against more well-known games. You do not like Jet Force Gemini, we get it! That doesn't mean it doesn't deserve to be here. The theme of this contest was that every game deserves to be here, large, small, or weeaboo.
Third, out of the 8 nominations cut, only 1 was a western game, and 6 of them were games from series already represented in the contest.
