As others have noted, it all depends on your visual style and
the kind of game you are making. There are some possible solutions
from which you can pick depending on what your goals are and what
works for your particular case:
1. Upscale the pixels to huge blocks. This works if you aim for
retro feel, although it is really getting old.
2. Downscale to match the screen size. This works especially well
when your game already does scaling, like zooming and such.
3. Scroll the playing area. Some games will only show you a part of
the playing area at a time, and either let you scroll freely or
scroll automatically following the player character. In such games
it often works to just show more of the playing field on
higher-resolution displays, allowing for more comfortable play but
not really changing the artwork or game rules.
4. Fill the remaining portions of the screen with the user interface.
For example, in a low-res version the inventory can be accessed
by entering the inventory mode, when the menu will replace the
normal view. In hi-res mode the menu may be displayed at all times
on the side of the screen. This is easiest if you only target a few
selected resolutions.
5. Make your game run in a window of fixed size. Let the players have
their music player, twitter client, text viewer with game's walktrough
or whatever they want opened side-by-side with it. Or even have several
windows, like Angband does -- then it becomes like 4.
6. Completely re-do all of your graphics for several different resolutions.
This is usually an insane amount of work and unless it's very important
to you, I wouldn't recommend it. Or you could have some ready graphics
that already comes in many sizes -- like the Tango icons.
7. Run full screen and force switching to the mode you want. This may look
very bad on displays with fixed native resolution and with different aspect
ratio than what you expect.
8. Scale the parts that can be scaled easily (like the map), but leave the rest
at constant resolution (like the icons on the map).
You will usually want to mix and match these in your actual games.
