Okay I'd rather have Samorost 3 than Loom 2, for obvious reasons to anyone who has played both. I mean, if you already set expectations by doing a sequel, the cynical me says financial concerns may've been put ahead of the experience.
A much better approach is to forget about the "2,3,4," sequel deal and use a sub-title (like Assasin's Creed did recently). This emphasizes that this is part of the same world but not necessarily something that should be directly compared.
I wish Ubisoft wasn't so stuck on the mechanics that weren't that good in the first place in the AC series. I got frustrated with the first AC within a hour - all the nice sceneries wasted on rather mind-numbing gameplay. Imagine if they had put a proper game there, something like Myst: URU but in AC setting and bit faster progression with action optional depending on what you do.
I could definitely see adventure game like Indy 3/4 in that AC style visual environment - you could choose whether to do puzzles/conversation/action to progress in freeform way, with no flashy gui's or tutorials popping up - if you want to fight go find some teacher inside the game world (but make that optional). (and have locations of varying style instead of time travel gimmicks).
