Hmm, I won't include evolutions, but I can include a mega evolved form :3! So for example a random encounter mega luca as a completely independent mon.
By the way, can I ask a question? If you do add mini-endings where we get married to one of our Pokémon (you already know my choices), is there a chance of seeing a possible pregnancy and children from our hero and his Pokémon? Just out of curiosity. Oh, damn... That would mean adding a small customizer for our hero, wouldn't it? Or does he already have a look? It would be interesting to see how he would look in these endings.
Hmmm, I haven't seen many games about pregnant women, but I can say that most of them stop at pregnancy. However, I have an idea: create two or three artworks - the first one featuring a married hero and a Pokémon, the second one about pregnancy, and the third one with a child. Again, this is just a suggestion, but if it's possible, keep it in mind for the future. Alternatively, you can conduct a survey to determine whether others want to see such content. =)
