that could get a bit tiresome after a few characters, i'd prefer pop-ups the first time you do stuff. Also its not that original :/ but i love the idea of escaped holograms being a side-quest which is associated with the training area
Lets not be defensive about our ideas - if we don't allow anyone to criticize them, they will not develop and flaws in them will persist.
I actually think this a really good idea. Also only being allowed to spawn creatures you've encountered and logged in your journal is a good idea too, but i don't think you should be able to spawn bosses.
I personally would like to be able to spawn bosses, but only ones you have previously defeated. Not for practice, though, just for the fun of it.
I think we should be able to spawn bosses previously defeated for fun, try other ways to kill them and remember how we killed them. Like if you can't defeat a boss, but you've defeated a boss like that (because they are generate randomly) you can try to find the way you beat him to adapt it to the harder boss.
thats a great idea, perhaps the training room could instead be a planet, to be able to train in different biomes, or maybe the training room itself could generate different biomes
