From my PoV, the most important thing is knowing exactly where to make important saves, which the TLWiki doesn’t seem to do. I mean you can probably work it out but it’s good to have it thrust right at you with them labelled Save A, Save B etc. I especially like to know which is the first really important save is, even more so if it’s a long way into the VN so you don’t have to replay from the start if you mess it up ( and my first playthrough will be blind so I surely will mess it up!).
This is helpful for those with limited time to know where to reload and make the different choices for different routes - even if it might compromise seeing absolutely everything in the VN - because even with auto skip some may not want to go further back than absolutely necessary.
