if u are able to find one u should try to get a car adaptor to charge ur switch since switch has bad battery life
dark souls is good but some parts of it can be confusing enough that its possible to get stuck without a walk-thru
i needed to use a walk-thru bc i couldnt find one of the first areas
its on sale i think
i have the digital version bc it has a small file size
hollow knight is good too and it does have some similarities to dark souls (strategic combat, dying dark fantasy world, drop currency at location of death) but its much easier to understand
also on sale
another game i havent seen mentioned in this thread is Okami
its a really good game and its also cheap
its a game by the creator of bayonetta
its a port of an older game (from 2006) but it aged well
its basically like zelda (like ocarina of time style zelda) with a painting mechanic
i played it on a long road trip and can confirm it is a good road trip game
it also has a heart-warming story
also on sale
also minecraft but u might have to download lots of updates b4 u go on the road trip
i played this on the road trip too
also monster hunter generations ultimate
this game is also too vague sometimes, like it wont tell u what the required quests are (besides urgent quests), but if u want to do all the quests then u can beat it that way too i guess (some quest types are annoying tho like ones where u have to transport an item without dropping it)
also i recommend doing the tutorials for each weapon to find the one u like
theres also a demo of this game in the eshop and u can try out all the weapon + hunting style combinations and theres 3 monsters/bosses to fight
also on sale i think
if u miss the sale, then buy physical bc a brand new copy of the physical version is cheaper than downloading it (in us physical is $40 and digital is $60)
also stardew valley like what other ppl said
it actually has a shockingly huge amount of content
also on sale
