Hey Nik,

Sorry for taking so long to reply.

To create a table, try doing this: 
$dbh->do("CREATE TABLE `games` (`gamename` TEXT, `gamedesc` TEXT, `gam
+ecount` TEXT );");

Then, create a unique index on the table - the 200 is a length that you can modify if you want. 
$dbh->do("ALTER TABLE `games` ADD UNIQUE `UNQINDX` ( `gamename` ( 200 
+) )");

[download]

You should now successfully be able to use REPLACE on your table.

Taking a look at your code... 
my (@row, $gamename, $gamedesc, $gamecount);

# selecting count(*) will run faster
my $select = $dbh->prepare( "SELECT count(*) FROM `games` WHERE `gamen
+ame`=?" );

# column `gamecount` was labeled as `gamecounter`
my $insert = $dbh->prepare( "INSERT INTO `games` (`gamename`, `gamedes
+c`, `gamecount`) VALUES (?, ?, ?)" );

my $update = $dbh->prepare( "UPDATE games SET gamedesc=?, gamecount=? 
+where gamename=?" );

open (FILE, "<../data/games/descriptions.txt") or die $!;

    while (<FILE>) {
        chomp;
        ($gamename, $gamedesc) = split /\t/;
        $select->execute( $gamename );

        if ($select->fetchrow_array) {

           # WARNING: $gamecount isn't defined!
           $update->execute( $gamedesc, $gamecount, $gamename );
        }
        else {
           $insert->execute( $gamename, $gamedesc, 0 );
        }
    }

close (FILE);

I'm a bit tired, but I hope this helps! Note my comments within the code.

The error in your message below indicates that the execute method isn't receiving the correct number of variables. Check to see that the file is tabbed correctly.

Best,
