I have been playing BS for almost 2 years, but find it frustrating that older appliances are eternally "locked" because the goals to unlock them expired before I started to play. While I am not opposed to building new appliances, I believe many players would like to have access to those older appliances. In turn, for appliances of which I have mastered all the recipes, some new recipes would be welcome. (Like the Valentine's Day cupcakes on the standard ovens!)
Case in point: many players were disappointed that we did not get St Patrick's day goals/updates and had repeat themes like bees & honey or Tea time for the month of March. For the appliances, wouldn't have been great if we got NEW recipes on the older appliances (like the honey drink maker) that relate to the reoccurring themes rather than just reboots of themes with similar appliances? For players that don't have the appliances (like the Dublin Oven), they get a chance to start from the beginning of the goal to unlock the appliance, while players that already have the appliance can dust it off and start on goals to unlock the new recipes! Win/Win.
Would be interested in other perspectives, especially those veteran players.
