It is worth thinking about the setting too. Games with a drawstring bag or a tin survive being thrown in a rucksack better than a large flat box. For a caravan or a beach hut with limited space, pick a few small games rather than one big one, so you can match the game to the mood without taking up a whole shelf.
Home escape room games take the idea of a real-life escape room and pack it into a box. You work through a story by solving a chain of puzzles, cracking codes, reading hidden clues and combining objects until you reach the final answer. Most are built for two to six players working together, which makes them a good fit for a family evening or a small get-together.

Slower, more thoughtful word games suit older children and adults who like to plan a high-scoring play. These reward a wider vocabulary and a bit of tactics, so they are better kept for players who enjoy taking their time. If you are buying for a mixed-age family, a fast game is usually the safer bet, since it keeps the youngest involved rather than left behind.
To compare word games by pace and age suitability, and see which reward speed versus vocabulary, take a look at the word games at the Genius Square puzzle game.
The trick to a family game night that does not fall apart is picking games that work across ages. Younger children lose interest when a game runs too long, and older players switch off when the rules are too thin. A mix of one quick game, one party game and one slightly longer game usually keeps everyone at the table without anyone getting bored or overwhelmed.
