Most of us possibly missed Vegetablets Go by Japanese delevoper Tulip House. Guide your bear and carry the crops (cabbage, spinach, strawberry) in the field to the harvest point! There were 10 NES and 10 FAMICOM copies and they are sold out. Keep an eye at the discussion over at NintendoAge.
There is a little chance to see more cartridges being sold in the future. Let’s hope for those, who can’t grab a copy in time, there will be a free ROM sometime in the future.
