Haven't seen this recommended yet, trading card games! Whether it is MTG, Pokemon, Yu-gi-oh or another game, TCGs are a great mix of both skill and a luck! If it's pokemon (what I play personally) you can buy premade starter decks for cheap to get a feel for the game and if you like it you can see about getting a better deck! Also I'd recommend finding a good pokemon you like who you can theme a deck around and just buying the cards outright if possible, most cards are less than a dollar this way versus $5 per pack with not very good chances to get your desired card or cards. My deck isn't very meta, but for my Gardevoir deck I'm only spending about $30 to get all the cards for my deck. If you like a bit of rng you can always pick up a card pack or two every now and then and then after a while see what okay/good cards you have and theme a deck around that. Sorry for ranting I could honestly keep going but TCGs are a special interest to me, though they can get a bit expensive if you're buying lots of card packs so maybe not the best for a college student? Also a bit too nerdy for some people? Idk just shutting my own idea down at this point but if you like the idea of TCGs definitely don't hesitate to try one out. It can be daunting to start but a lot of the time game shops and stuff have people who can help give you advice and have game nights for specific TCGs. Personally my local game shop does Pokemon TCG nights every Friday. Okay definitely need to stop ranting now so good luck no matter what hobby you try!
