Mods can help a lot!
For example, there’s a mod to increase the text size: https://www.nexusmods.com/eldenring/mods/650 (It hasn’t been updated for awhile, so I don’t know how well it’d work for recent patches)
If the game is just too difficult, there are also mods to help with that. Mods can adjust the difficulty, add FP regen, unlock summoning, etc., or completely overhaul the game (I had a lot of fun with the Convergence mod last year)
Fortunately, price info is actually tracked! If you use the SteamDB browser extension you can see the historical low price right on a game’s product page on Steam.
For example, Terraria is on sale for it’s 2 year low price of $4.99, but the lowest it’s ever been is $1.99 (a little over ten years ago).
