They haven't said a word about a PC version of TLR Remastered, even though it's a matter of time (there's no reason to delist the original from Steam otherwise). Give it a couple months and we'll know.
There's the comparison video I linked, which does a decent job at showing the texture/lighting improvements.
The game's wiki is an invaluable resource in general. A few super-dedicated fans of the game worked for years to make a nearly 4,000-page resource for virtually everything in the game, and it's been a huge help in putting together stuff like my missables cheat-sheet and other things.
As far as random pointers go:
- Try to keep the overall number of battles you fight on the low side. You can aggro enemies by initiating a battle just outside the battle radius - that plus Timeshift will ensure you consistently get several groups linked together.
- Disable some skills on your party members to ensure they learn fewer, but more powerful, skills. Especially do this for Rush, as he can eventually learn pretty much any non-Unique skill.
- Watch the radar during battle for opportunities to flank the enemy.
- You can level up Mr. Diggs's abilities easily and early in Dillmoor; there's a mining spot just to the right as you enter (leave and re-enter to reset his digs count). His stats and abilities and digs count all carry over through New Game Plus.
- Do as many quests as you can when you get them; quite a few are either missable or cannot be completed after certain points in the story. Check the pubs and guilds on a regular basis, and talk to everyone. Talking to otherwise-unassuming people in this game can open up entire new areas to explore on the map, it's that important.
- In general, just craft equipment for Rush. You can make stuff that your party members will want, but they won't usually have them equipped for long. Notice how your party members will often ask for materials, and then take them after battle? They're using those to make their own equipment, which is usually better.
- Choose formations wisely. The Orb formation is great for mages who want to practice their skills (it reduces the AP cost), but it nerfs physical attacks by quite a bit. Play around with formations and always be on the lookout for new ones (get them mostly from Guild quests).
- Check to see what captured monsters can be "split" into. Some party members may be on the lookout for the resulting components.
- Save often and in multiple slots. There are a lot of areas where you either can't easily escape or can't leave until you've killed a boss (the game will warn you in the latter case).
- Have fun! The game's battle system is ridiculously deep but it feels great to master it. Ask away ITT if you have any questions.
