Videogame wise…. Depends on what system you have, as there are plenty of great games available. List the systems you have, and it’ll make it easier to offer suggestions.
As for RPGs, don’t be afraid to buy the ones that everyone mentions, because we talk about them for a reason. Grab a shopping trolley, go into your nearest games shop and ram it into the shelf with Bioware/Obsidian/Square/Bethesda/Namco games, and you’ll come home with more classics than you know what to do with.
Seriously, you can’t really go wrong if you stick with these companies. They hit far more often than they miss.
